A four quadrant power module with lower substrate parallel power paths and upper substrate equidistant clock tree timing utilizing parallel leg construction in a captive fastener power module housing.

High temperature equalized electrical parasitic power packaging method for many paralleled semiconductor power devices

A half bridge gate driving circuit for providing gate driving circuits in a bi-hecto celcius (200 degrees celcius) operating environment having multiple functions including combinations of multiple level logic inputs, noise immunity, fault protection, overlap protection, pulse modulation, high-frequency modulation with transformer based isolation, high-frequency demodulation back to pulse width modulation, deadtime generator, level shifter for high side transistor, overcurrent protection, and undervoltage lockout.

High temperature half bridge gate driver

High temperature gate driving circuits with improved noise resistance and minimized loss are implemented with high temperature components with a reduced size magnetic isolation transformer. Input broad-pulse width modulated signals are converted to offsetting narrow pulses to cross the reduced size magnetic transformer minimizing isolation losses. One embodiment teaches time and voltage offset narrow single pulses that control a set and reset regeneration of the pulse width output on the secondary side of the transformer. Another embodiment teaches multiple concurrent voltage offset pulses to cross the transformer and charge a threshold capacitor for both filtering noise and controlling the pulse width regeneration on the secondary side of the transformer.
