Characteristics for the Power Module for solid state high frequency welder

Model configuration

Characteristics:

Using high-power MOSFET, the equipment efficiency≥90%.
Using dual-loop PI regulator of voltage and current, the power range is adjusted from 0-100%.
Using the computer to control the voltage regulation, the adjustment is stable with high precision and small harmonic wave interference.
It has fault protection system with over-voltage, over-current and lack phase etc.
