ABSTRACT:
A switching power supply comprising a converting circuit; an analog-to-digital converter for converting a signal referring to an output signal from the converting circuit into digital form; a parallel-to-series converter for converting a bit train signal containing the output signal from the analog-to-digital converter into a pulse train; an isolation means for transmitting the pulse train to the primary winding of a transformer while concurrently electrically isolating the pulse train; a series-to-parallel converter for demodulating the pulse train into a parallel signal; and a control circuit. The converting circuit has a switching device which turns ON and OFF the voltage applied across the primary winding. The converting circuit provides rectification and smoothing of voltage induced in the secondary winding of the transformer, and supplies an output DC voltage to a load. The control circuit calculates control output for regulating the output voltage from the converting circuit which is received also by the series-to-parallel converter, to a given voltage. The control circuit further acts to produce an output signal which turns ON and OFF the switching device.
