XVC768102 3BHB007211R102 main control board

XVC768102 3BHB007211R102 Main control board The main control board is the control center of the drive, including four parts of the circuit, including control power supply, modulation pulse generation, control mode and protection logic. It accepts signals from the panel and the external control interface to control and protect the work of the radio frequency unit, and at the same time it outputs the status signal of the drive to the panel and the external control interface.

The IGBT main control board is mainly based on the high-frequency induction heating main control board and two drivers. The high-frequency board technology uses SG3525A as the PWM pulse formation, the output pulse frequency range is 20KHZ-60KHZ, the pulse interval is 180 degrees each other, and the dead time Can be adjusted by yourself. The utility model is suitable for voltage regulation and power regulation of a chopper used in an IGBT full-bridge inverter series resonance induction heating device.
