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.
