Abstract

A two switch forward converter based 50 V, 150 A water-cooled DC power module has been developed for biasing solid state RF amplifiers. A detailed analysis has been carried out on various failure modes of this power module and the results are presented in this paper. The simulation of various failure mode scenarios has been carried out in OrCAD PSpice Cadence software. These failure mode scenarios include open circuit and short circuit across IGBT switches, short circuit across output capacitor and bridge rectifier diodes etc. The response of power module during these failures is studied through various waveforms obtained during simulations and necessary measures are taken to reduce the occurrence of these failures. The wound components of this power module have been designed to withstand short circuit for sufficiently long duration. Suitable multilevel circuit protections have been implemented in this power module through fuses, MCB, contactor and digital module controller for its reliable operation.
