Abstract
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.
