Inventor: NORIMATSU SEIJI
IPC: H02M5/453
Filed: 1998-03-03
Abstract: PROBLEM TO BE SOLVED: To provide a voltage resonant converter which can be operated stably by an AC power source. SOLUTION: DC bias voltages for FETs 4, 5 are formed from a rectified output of a full wave rectifier 15 by using resistors 16-18 and a constant voltage diode 19, thereby always obtaining constant DC bias voltages irrespective of AC input amplitudes. The amount of feedback from a feedback coil L2 to the FETs 4, 5 is limited to be in a range such that the FETs normally operate. As a result, operation of the FETs becoming unstable can be prevented and breakdown is generated, when the AC input changes in a wide range and the amount of feedback from the feedback coil L2 increases. By installing a constant voltage forming means which uses the constant voltage diode 19 and forms the DC bias voltage and a feedback amount limiting means constituted of constant voltage diodes 21, 22, a voltage resonant converter which can be used by an AC power source can be provided.
