Title: Power source device
Inventor: NISHIMURA KOJI
IPC: H02M7/537
Filed: 1986-08-29
Abstract: PURPOSE:To increase a dielectric strength between a collector and an emitter and prevent the malfunction of a power source device, by connecting the emitters of switching transistors commonly and grounding the connection or the like. CONSTITUTION:Switching transistors Q1, Q2 are driven by the output of an oscillator OSC through base control transistors Q3, Q4 to switch a power source vs1 and supply the output to a load 8 through a transformer M. The bases of the switching transistors Q1, Q2 are connected commonly and are grounded through a resistor Rb. A voltage is generated on both terminals of a resistor Rb by a current, conducted through the switching transistor Q1 or the transistor Q2 under ON operation,while the transistor Q1 or the transistor Q2, which are being put OFF by the voltage, is biased reversely, therefore, the dielectric strength may be increased due to the reverse bias condition.
