ABSTRACT:
A power source apparatus includes a rectifier, a smoothing circuit, an output control circuit, a switching circuit and a voltage detecting circuit. The voltage detecting circuit has a smaller time constant than the smoothing circuit. A semiconductor switching element in the output circuit is turned on and off such that it is only on when both the switching circuit and the voltage detecting circuit determine that the rectifier output has exceeded a predetermined level. The time constants of the voltage detecting circuit and smoothing circuits can be set such that the output is switched off at substantially the same voltage level when different loads are applied to the output circuit.
