摘要：
A power converter circuit is disclosed utilizing pulse width modulation for power regulation. A rapid acting surge protection circuit for the power driving switch is operated from a string of zener diodes to disable the power switch. A base charge removal circuit is included for dissipating accumulated base charges on the driving transistor without the need for a bipolar driving signal for the power transistor.
