Control IC

EG8010 (SPWM generator) + IR2110 (gate driver)

Input Voltage

DC 12V–24V (Logic power supply, typically 12V)

Output Frequency

50Hz/60Hz (Adjustable via jumper or EG8010 settings)

SPWM Carrier Freq.

20kHz (Default, reduces audible noise in transformers)

Output Voltage

AC 110V/220V (Depends on H-bridge and transformer)

Gate Drive Output

4-channel (For H-bridge MOSFETs/IGBTs, up to 500kHz switching)

Gate Drive Voltage

10V–20V (IR2110 bootstrap, supports high-side drive)

Protections

- Overcurrent (OC) via shunt resistor

- Undervoltage Lockout (UVLO)

Cooling

Passive (no heatsink required for driver board)

Interface

- Potentiometer for frequency adjustment

- Jumper for 50Hz/60Hz

Dimensions

Approx. 65mm × 45mm (Standard EGS002B size)
