Dear Reader

This unit is about 2500Watt based on half-bridge resonant topology (Ath1).

The controller IC is NCP1399AM.

SR stage handled by SRK2001.

PFC output: about 400volt generated by NCP1654

Feedback circuit: Ath2

Circuitry around IC (Atach2)

I have not found any fault throughout the circuit but still, the tank is not triggered.

I greatly appreciate any feedback, comment or suggestion.
