Title: Stepping up switching power supply
Inventor: MORITA KOICHI
IPC: H02M3/155
Filed: 1990-11-29
Abstract: PURPOSE:To reduce noise and power loss by connecting a capacitor between one end of a first reactor and one end of a second reactor. CONSTITUTION:Since a capacitor 12 is charged in an off-period of an FET 4a, a diode 9 is reversely biased by the capacitor 12 in an on period of the FET 4a and placed in an off-condition. Consequently, a current 13 is allowed to flow in the capacitor 12 through a circuit formed of a power supply 1, FET 4a, capacitor 12, second reactor 10 and a smoothing capacitor 11 or a load 8. When the FET 4a is turned off, surge voltage is generated because the first reactor 5 has leakage inductance, but a closed circuit, comprising the first reactor 5, power supply 1, diode 9 and the capacitor 12, is formed to absorb the surge voltage by generating a current to flow in the capacitor 12.
