Filed: 1995-11-21
Abstract: PROBLEM TO BE SOLVED: To improve a power factor by a method wherein switching devices which are operated in a positive side half cycle period and in a negative side half cycle period are combined to compose a switching circuit. SOLUTION: If driving signals are supplied to switching devices 12 and 13 when a commercial power supply voltage is in a positive side half cycle period, an operation current route is as follows: A commercial power supply 1 and a capacitor 3 → a reactor 4 → a switching device 12 → from the source to drain of a switching device 13 and the parasitic diode 13' of the switching device 13 → the commercial power supply 1 and the capacitor 3. An energy is stored in the reactor 4. Then, if the driving signals are turned off, the energy stored in the reactor 4 is discharged through a route as follows: The reactor 4 → a diode 14 → a capacitor 7 → the parasitic diode 13' of the switching device 13 → the capacitor 3 → the reactor 4. Thus, the capacitor 7 is charged by the energy and a stable DC voltage can be supplied to a load 0. Further, in the negative side half cycle period, the same procedure is repeated. As a result, a power factor can be improved significantly.
