Title:
VOLTAGE RESONANCE TYPE HIGH FREQUENCY SWITCHING CIRCUIT
Document Type and Number:
Japanese Patent JPS57138868
Kind Code:
A
Abstract:
PURPOSE:To facilitate the control of an output power of a switching circuit and to improve the utility of a transformer by providing a voltage cotrolled magnetic amplifier at the secondary side of a transformer and providing further a current smoothing choke coil and a current regenerating diode. CONSTITUTION:A voltage controlled magnetic amplifier 20 is provided at the secondary side of a transformer 13, and a load current smoothing circulating circuit 26 having a current smoothing choke coil 22 and a current regenerating diode 24 is provided. One cycle of the secondary output of the transformer 13 is used for the gate cycle of a magnetic amplifier 20, and the other cycle is used for a resetting cycle. The voltage of a resetting cycle is controlled by the variable resistor 19, thereby controlling the output power supplied to a load 23.
