Quick Maintenance


The circuit is a current-fed inverter (CFI) with an inductance located between the DC and the HF stage, thus the inverter is naturally protected against load short circuit. The output circuit is a parallel type: load and inverter impedances are naturally matched, then no output transformer is required and the overall efficiency increases.

Typical layout includes a power supply cabinet containing transformer, DC inductance, SCRs bridge and auxiliary circuits and a second cabinet, the welding head, where the mosfet modules, capacitors and bus-bar are contained.

The input transformer is provided to achieve insulation from the mains and to optimize the exploitations of the Mosfet based inverter
