Title:
SWITCHING POWER SUPPLY DEVICE
Document Type and Number:
WIPO Patent Application WO/2014/109304
Kind Code:
A1
Abstract:
A pulse voltage is applied to one terminal of a resistance element (R1). One terminal of a resistance element (R2) is connected to the other terminal of the resistance element (R1). A capacitor (C1) is provided between the other terminal of the resistance element (R2) and ground. A diode (D1) and a capacitor (C2) are connected in parallel with the resistance element (R1), and a diode (D2) and a capacitor (C3) are connected in parallel with the resistance element (R2). The diode (D2) is arranged in the reverse direction with respect to the diode (D1). Transistors (Q1, Q2) have a control terminal connected to the other terminal of the resistance element (R2) to turn an input power supply (E1) on and off. A transformer (16) transforms the AC voltage generated by turning the transistors (Q1, Q2) on and off.
