Filed: 1990-01-22
Abstract: PURPOSE:To reduce loss at the time of turn OFF by connecting a variable capacitance capacitor in parallel with a switching element in a switching power supply having the switching element connected between one and the other ends of a DC power supply through a transformer or a reactor. CONSTITUTION:During ON interval of a switching element 4, source voltage is applied on the primary winding 3 and a corresponding voltage is induced in the secondary winding 5. When the switching element 4 is turned OFF, collector current of the switching element 4 starts to decrease and a current flows as the energy stored in the primary winding 3 of the transformer 2 is discharged. At this time, a flyback voltage is produced but since a variable capacitance capacitor 13 is connected in parallel with the switching element 4, the flyback voltage is absorbed and the voltage across the switching element 4 rises slowly.
