ABSTRACT:
A power source circuit converts direct: current (DC) power into alternating current (AC) power having a required frequency, and provides DC output power according to the AC power. The power source circuit comprises an oscillator for providing a control signal that determines a converting frequency of the AC power; an element provided for the oscillator, having temperature characteristics for increasing the converting frequency at a low temperature; and a device for determining the converting frequency of the AC power according to the control signal provided by the oscillator.
