Abstract

PURPOSE: To provide the subject circuit wherein a phase componenting circuit which detects a main circuit current and varies the conduction control angle of a switching element by the increase or decrease of the current is provided, and the variation in the characteristics at the time of power source variation is compensated and the phase control is performed accurately, thus improving the operation reliability.
CONSTITUTION: The AC end of a rectifier D2 is connected in parallel to a series circuit of a capacitor C2 and aresistor R2, and a series circuit consisting of a constant-voltage element Dz3, a resistor R4 and a capacitor C3 is connected to the DC end of the rectifier. The detection output of a detection coil L2 which becomes the secondary side of an inductance element L1 is rectified by a rectifier D1 to charge the capacitor C3, and a phase compensating circuit is constituted by an element encircled by broken line. By the operation of said phase compensating circuit, the phase control angle becomes small or great. As a whole, the main circuit current becomes constant, the phase control is performed accurately and the operaton reliability can be improved.
