ABSTRACT:
A switching-mode, blocking oscillator based power supply employs proportional base drive and an improved design of rise-time suppression to improve effeciency and reliability. Current limiting elements cooperate with pass transistor control circuits to provide abrupt and power-efficient primary circuit switching.
