ABSTRACT:
A switching regulator is provided with a separate or isolated d-c output for operating the switching pulse generating circuits. A large value resistor coupled between the d-c input line and the isolated d-c output will charge the filter capacitor to a higher than normal voltage. A zener diode string is coupled across the filter capacitor. The zener diodes in combination have a higher than nominal zener voltage. The diodes will respond to the capacitor voltage and develop a starting pulse that initiates the power supply when it is first energized.
