Problem
SPEAR 3 experienced MCOR30 bridge MOSFET failures during bulk power supply turn on
It was determined that, with a fixed front panel controlled set-point, the bulk power supply output voltage was rising too quickly. The MCOR crate auxiliary power supply oscillated
Solution and Requirements
Soft-start circuit to slowly apply the bulk power supply set-point (and hence ramp the output voltage) after bulk power supply turn on.
