1. Pulse waveform of induction melting furnace inverter circuit:

Pulse characteristics: single pulse, pulse amplitude is generally 3 ~ 6V, pulse width should be greater than 30μS.

2. Induction melting furnace rectifier output voltage waveform:

Rectifier phase shift angle Rectifier bridge output voltage waveform Rectifier terminal voltage waveform

3.Inductive melting furnace incoming line sampling current waveform:

The oscilloscope probe is connected to any set of outputs (68,69), (69,70), and (70,68) of the 5: 0.1 transformer: when the DC voltage is high and the α angle is close to 0 °, the top is getting closer and closer Straight.
