Inventor: WATANABE KAZUTO
IPC: H02M3/28
Filed: 1991-12-12
Abstract: PURPOSE:To object switching power unit which is highly efficient and little in heat generation of a switching transistor. CONSTITUTION:A transistor 3 for shortening of turn off time is connected to a switching transistor 2, and the base of the transistor 3 is connected to the common junction between the capacitor 4 and the resistor 5 constituting a snubber circuit 24. By this constitution, when the switching transistor 2 is turned off by the saturation of the base, the transistor 3 for shortening of the turn off time is turned on by the voltage generated in a snubber circuit 24, and it draws out the charge accumulated in the switching transistor 2 and turns off the transistor, thus the turn off time is shortened. Hereby, the switching loss of the switching transistor 2 decreases, and the device is made highly efficient.
