Abstract
A method of controlling a current resonant parallel type switching regulator comprises providing a current circulating circuit for preventing a circuit loss increasing phenomenon from occurring due to an increase in a resonant current caused by an increase in a resonant voltage when an output load current is reduced, forming a closed circuit which connects the opposite terminals of a resonant circuit for inverting the polarity of the charge on the resonant circuit once, and then starting the operation of the regulator. The resonant current is reduced so that an excessive power is not supplied at a low load. Stresses on the switching elements and circuit losses are minimized.
