Title: Switching converter circuit
Inventor: OGURA NOBUO
IPC: H02M3/28
Filed: 1993-12-27
Abstract: PURPOSE:To realize a constant voltage control by a method wherein an orthogonal transformer is employed as the driving transformer of a current resonance converter and a control current in accordance with a rectified and smoothed voltage level is supplied to the control winding of the transformer and the switching frequency of a switching transistor is made to be variable. CONSTITUTION:Driving windings LB1 and LB2 and a resonance current detecting winding LD are wound in an orthogonal driving transformer T1 as non-control windings. Further, a control winding LC1 is wound in the transformer T1. If the voltage of a commercial AC power supply AC is elevated, a control current IC which is applied to the control winding LC1 through a resistor R1 is also increased but the inductances of the driving windings LB1 and LB2 are reduced. In accordance with the reduction of the inductances, a switching frequency is increased. As a result, even if a rectified and smoothed voltage Ei is elevated, a DC voltage VO is kept constant. With this constitution, a starting circuit and an IC driving circuit are not necessary, so that the cost reduction and the miniaturization of a mounting board can be realized.
