The sine wave high-power IGBT module control driver board is actually the rear-stage DC-to-AC part of the inverter, which converts the front-stage high-voltage direct current into an AC 220V output device.

Now in the market, there are too many high-power IGBTs that are disassembled. The power is high and the price is cheap. I want to use these good resources to make a high-power sine wave inverter. If I want to make good use of these high-power IGBTs as an inverter , The sine wave control board should pay attention to two points, the dead time during work and the switching frequency during work, these two points are very important and fatal. The dead time of the control board is 2us, and the dead time of this board is 2.0us, which can be adapted to different sizes of IGBT modules, the carrier frequency SPWM is 16.000KHz, the control board has 50Hz/60Hz switching, with switch control, etc. Board size ：15*6.5cm, this control driver board uses HCPL-316 drive protection circuit: integrated VCE saturation voltage drop detection, undervoltage lockout, soft shutdown and isolated fault feedback; always detects the saturation voltage drop of the chip 14 feet, when the voltage Over 7V, the output voltage of VOUT11 pin becomes low, FAULT (6 pin fault output) is low, and it is in the protection state.

New features: V3.0

1. Pure full high frequency inverter conversion circuit

2. Realize single-phase high-power inverter output

3. The output current. The power is constant and adjustable, which can realize the soft start of the motor

4. In constant current output mode, the output is always sine wave waveform

5. In the constant current output mode, the output is lower than 150V, and the output is turned off in 7 seconds

6. Under the condition of not using the display screen, the undervoltage protection point can be set from 0-220V

7. Support voltage, current, power display and adjustment

The IGBT module drive control board: the default startup time is 7 seconds, the dead zone is 2uS, and there is no output 150V undervoltage protection, which is convenient for beginners to install and use

Another program: start time 7 seconds, dead zone 2uS, output short circuit and 150V undervoltage protection, start adjustable constant current output, suitable for mass production and electronic master use.
