ABSTRACT:
A switching power source of a voltage resonant type having a circuit for detecting the lowest point of voltage applied to both ends of a switching element, a time signal generating circuit which is activated concurrently with the turning ON of the switching element to output a predetermined time signal, and a circuit for inhibiting the turning ON of the switching element based on the lowest point detection signal, while a time signal is outputted from the time signal generating circuit.
