Title: Resonance type switching power supply
Inventor: TAKAHASHI YUKIO
IPC: H02M3/28
Filed: 1991-03-28
Abstract: PURPOSE:To provide a switching power supply which operates with low loss over a wide range of input voltage. CONSTITUTION:At OFF timing of a switching element SW, a resonance circuit is formed of the primary coil L1 of a transformer (50) and a resonance capacitor CRES and the voltage across the controlled electrode of the switching element varies sinusoidally. A voltage detecting circuit comprising a diode D2, a resistor R9 and a transistor Q0 detects a minimal point of the voltage to trigger CT terminal of a control circuit(20). The control circuit(20) provides a high level output to OUT terminal thereof for a predetermined time after the trigger point at the CT terminal thus turning the switching element SW ON. Since the switching element is turned ON at a time point when the voltage across the controlled electrode has a minimal level, switching loss can be neglected and an IGBT having low ON resistance can be selected as the switching element. Furthermore, a delay circuit comprising a resistor 10 and capacitors C3, C4 functions to trigger the CT terminal of the control circuit(20) at a minimal point of the voltage across the controlled electrode at all times, the switching power supply operates with low loss over a wide range of input voltage.
