Figure 6-1. EG8010+IR2110S Sinusoid inverter (unipolar modulation) Note: 1.
In constant frequency mode, 50Hz(FRQSEL1,FRQSEL0=00) or 60Hz(FRQSEL1,FRQSEL0=01), Pins FRQADJ/VFB2 and VVVF have no effect. AC output voltage is adjusted by the feedback resistor R23. This application can be used in as dimmer and voltage regulator.
2.
In variable frequency and constant voltage mode (Pin VVVF at “0” low electrical level) 0～100Hz(FRQSEL1,FRQSEL0=10)or 0Hz～400Hz(FRQSEL1,FRQSEL0=11), pin FRQADJ needs to connect an external adjustable resistor. Pin FRQADJ adjusts output frequency and R23 sets output voltage.
3.
In variable frequency and variable voltage mode (Pin VVVF at “1” high electrical level) 0～100Hz(FRQSEL1,FRQSEL0=10) or 0Hz～400Hz(FRQSEL1,FRQSEL0=11), pin FRQADJ needs to connect an external adjustable resistor. Pin FRQADJ sets output frequency and voltage. EG8010 maintains V/F as a constant. R23 sets output frequency at 50Hz when voltage effective value is 220V.

In constant frequency mode, 50Hz(FRQSEL1,FRQSEL0=00) or 60Hz(FRQSEL1,FRQSEL0=01), Pins FRQADJ/VFB2 and VVVF have no effect. AC output voltage is adjusted by the feedback resistor R23. This application can be used in as dimmer and voltage regulator.
5.
In variable frequency and constant voltage mode (Pin VVVF at “0” low electrical level) 0～100Hz(FRQSEL1,FRQSEL0=10)or 0Hz～400Hz(FRQSEL1,FRQSEL0=11), pin FRQADJ needs to connect an external adjustable resistor. Pin FRQADJ adjusts output frequency and R23 sets output voltage.
6.
In variable frequency and variable voltage mode (Pin VVVF at “1” high electrical level) 0～100Hz(FRQSEL1,FRQSEL0=10) or 0Hz～400Hz(FRQSEL1,FRQSEL0=11), pin FRQADJ needs to connect an external adjustable resistor. Pin FRQADJ sets output frequency and voltage. EG8010 maintains V/F as a constant. R23 sets output frequency at 50Hz when voltage effective value is 220V.

Figure 6-6. EG8010+IR2110S Sinusoid inverter (low power frequency transformer) Note: 1. T1 needs to use low power frequency transformer. Transformer filters PWM high frequency signal by connecting its secondary turns to a 2.2uF/400V capacitor of CBB. After filtering, it outputs 50Hz/60Hz sinusoid. 2. For full-bridge power MOSFET choose low Rdson MOSFET according to the input voltage.

micro corp. EG8010 Datasheets ASIC for single-phase SPWM control
8. Application note 8.1 AC Output Voltage Feedback EG8010 works under two modulation modes: unipolar modulation and bipolar modulation. Under unipolar modulation, only one bridge (EG8010 pins SPWMOUT3 & SPWMOUT4) is used for SPWM modulate output, and another bridge (EG8010 pins SPWMOUT1，SPWMOUT2) is used for fundamental wave output. A filter inductor needs to connect to SPWM output port, and a voltage feedback circuit needs to connect to SPWM inductor’s output port(as shown in Fig 8.1a). Under bipolar modulation, both bridges (EG8010 pins SPWM3, SPWM4, SPWM1, SPWM2) are used for SPWM output. Using both inductors will result in better flirting, a voltage feedback circuit need difference and feedback handling by voltage divider of both channels (as shown in Fig 8.c).
Under unipolar modulation, EG8010’s voltage feedback process is through measuring the AC voltage output of inverter by pin(13)VFB. Pin (16)FRQADJ/VFB2 only functions as FRQADJ, while VFB2 feedback has no effect. For such voltage sampling and feedback circuit shown in Fig 8.1a, it calculates the error between measured peak voltage and the sinusoid voltage reference (3V), and adjusts the output voltage accordingly. When output voltage increases, the pin voltage increases. The circuit does the error calculation and adjust range divider factor, therefore decreases the voltage to achieve voltage stabilization. Conversely, as the voltage on this pin decreases, the chip will increase output voltage.

Figure 8.1a EG8010voltage sampling and feedback circuit under unipolar modulation Figure 8.1bObservedSPWM unipolar modulation sinusoid output and VFB feedback wave
Figure 8.1b is the actual testing wave under unipolar modulation. EG8010 uses the peak point sampling to output voltage, which has advantages of accurate voltage stabilization and short voltage adjustment time. If output voltage is deviated by some reasons such as change of load or input voltage, EG8010 can recover to expected output voltage in one to three AC cycle.

micro corp. EG8010 Datasheets ASIC for single-phase SPWM control Under bipolar modulation, EG8010’s voltage feedback process is through measuring the output voltage of the left bridge by pin VFB2. Pin (16)FRQADJ/VFB2 only functions as VFB2 to measure the output voltage of right bridge, while FRQADJ has no effect at this time. For such voltage feedback circuit shown in Fig 8.c, it calculates the error between peak differential voltage measured by two channels differential feedback and the sinusoid max voltage reference (3V), and adjusts the output voltage accordingly. The circuit does the error calculation and adjust range divider factor to achieve voltage stabilization. Bipolar modulation can adjust to expected output voltage in one to three AC cycle as well.
Figure 8.1cEG8010Outputvoltage feedback circuit under bipolar modulation
To prevent output voltage is too low or too high when supply to the load, EG8010 has integrated overvoltage and undervoltage protection. Overvoltage protection is set at 3.15V with 300mS delay. Undervoltage protection is set at 2.75V with 3S delay. When either situation happens, depending on pin (9)PWMTYP’s setting, EG8010 will set the level of SPWMOUT1 to SPWMOUT4 at “0” or “1”, and shut down all power MOSFET to decrease the voltage to zero. Eight seconds after overvoltage or undervoltage protection activates, EG8010 will turn on power MOSFET for 100ms to re-determine output voltage. If overvoltage or undervoltage issue still exists, EG8010 will repeat the process above every eight seconds. If EG8010 runs regularly for more than one minute, it will zero the counter of overvoltage and undervoltage. However, if EG8010 does not function regularly after five 8-second cycle, it will complete turn off the output of SPWM unit. It needs a hard reset to start again.
8.2 AC Output Current Feedback Pin IFB measures the output load current for overcurrent protection detection. As the current sampling and feedback circuit shown in figure 8.1a, pin IFB’s reference peak voltage is 0.5V and overcurrent detection time is 600mS. If current is higher than inverter’s lad current by some reason, EG8010 will set the electrical level of SPWMOUT1 to SPWMOUT4 at “0” or “1” and shut down all power MOSFET to decrease the voltage to zero depending on pin (9)PWMTYP’s setting. This function mainly protects power MOSFET and the load. Sixteen seconds after overcurrent protection activates, EG8010 will turn on power MOSFET for 100ms to re-determine load current. If overcurrent issue still exists, EG8010 will repeat the process above every sixteen seconds. If EG8010 runs regularly for more than one minute, it will zero the counter of overcurrent. However, if EG8010 Copyright © 2014 by EG Microelectronics Corporation www.EGmicro.com 13 / 20
micro corp. EG8010 Datasheets ASIC for single-phase SPWM control does not function regularly after five 16-second cycle, it will complete turn off the output of SPWM unit. It needs a hard reset to start again. If in some scenarios the starting current is relatively high and it takes longer timeto start, which overcurrent protection is not suitable, Pin IFB can beconnected to the ground.
8.3 Temperature Feedback Pin TFB measures inverter’s environment temperature. Its main functions are overtemperature protection detection and displaying the environment temperature onto 12832 LCD. For temperature detection circuit shown in figure 8.3a, NTC thermal resistor RT1 and measuring resistor RF1 form a simple voltage divider circuit. Voltage changes as the NTC resistance changes, and thus we can acquire the corresponding temperature. Thermal resistor has 10k resistance at 25℃(B=3380). Pin TFB’s overtemperature voltage sets at 4.3V. EG8010 will set the level of SPWMOUT1 to SPWMOUT4 at “0” or “1” and shut down all power MOSFET to decrease the voltage to zero depending on pin (9)PWMTYP’s setting. Once overtemperature protection activates, EG8010 will re-determine environment temperature. If pin TFB ‘s voltage is below 4.0V, EG8010 will turn off overtemperature protection and the inverter functions regularly. If overtemperature protection is not used, this pin needs to be grounded.
Figure 8.3a EG8010 Temperature detection circuit
8.4 PWM Output Type Set Pin PWMTYP selects PWM’s output type. If PWMTYP is “0”, positive PWM output applies to the field where the dead level is meanwhile low(such as driver IR2110 or IR2106). Figure 8.4a is the output wave of pin SPWMOUT (high electrical level drives power MOSFET.)Figure 8.4b is an application schematic of drive IR2110 when PWMTYP= “0”.

8.5 Dead Time Setting Pin DT1, DT0 controls the dead time. Dead time control is one of the important characteristics of power MOSFET. Lack of enough dead time will result in the damage of MOSFET due to conduction. If the dead time is too long, it will lead to distortion of waveform and overheating of MOSFET. Figure 8.5a is EG8010’s four dead time control settings.“00”= 300nS. “01”= 500nS. “10”= 1uS. “11”= 1.5uS.

8.6 Frequency Setting EG8010 has two frequency modes: constant frequency mode and adjustable frequency mode. In adjustable frequency mode, EG8010 only uses unipolar modulation, and pin (20)MODSEL has to connect to low level. Pins FRQSEL1 and FRQSEL0 set the frequency mode. In constant frequency Copyright © 2014 by EG Microelectronics Corporation www.EGmicro.com 15 / 20
micro corp. EG8010 Datasheets ASIC for single-phase SPWM control mode, “00” outputs 50Hz frequency and “01” outputs 60Hz frequency. FRQADJ has no function in constant mode. Pin (16) is used as VFB2 voltage feedback circuit under bipolar modulation. In adjustable frequency mode, “10” outputs frequency in range of 0-100Hz and “11” outputs frequency in range of 0-400Hz. Pin FRQADJ adjusts the frequency as shown in figure 8.6a. Pin FRQADJ’s voltage varies from 0-5V, which is corresponding to the fundamental wave output frequency from 0-100Hz or 0-400Hz. This function accompanies with pin VVVF can be used in the single phase frequency transformer system.
Figure 8.6a EG8010 Frequency adjust circuit
8.7 VVVF (Variable Voltage and Variable Frequency Mode) To ensure motor’s electromagnetic torque is constant while varying frequency, setting VVVF=“1”will keep the value of V/F at a constant, Voltage is adjusted as the output frequency changes. When VVVF=“0”, output voltage is not changed when frequency varies.
8.8 Serial 12832 LCD Setting EG8010 supports 12832 LCD modules. It can display inverter’s voltage, frequency, temperature and current information to the user. Figure 8.8a shows how to connect EG8010 with 12832 LCD.
