ABSTRACT:
The invention discloses a switching regulator for use in a power supply system for an electric computer. The input from a DC or AC power supply is converted into the high frequency pulses, stepped up or down in voltage and rectified into the DC output to be supplied to a load. The power to be supplied to the load may be varied by changing the pulse duration of the high frequency pulses in response to the difference voltage representing the difference between the voltage across the load and the reference voltage. At starting, the internal circuits are biased with the power supplied from the power supply, but during the operation they are biased with said DC output or the output from the preceeding circuits.
