Abstract

PURPOSE:To enable the capacity of an inductor to be minimized and miniaturize the whole device at low cost, by charging the condensers of a smoothing device not only with low-frequency current but with high-frequency current. CONSTITUTION:During high pulsating current output from a rectifier 1, the condensers 9, 12 of a smoothing device 8 are charged via the rectifier 1, the condenser 9, a diode 10, an inductor 11, an inductor 14, a diode 13, the condenser 12, and the rectifier 1. They are charged with the frequency of pulsating current output, and so they are charged with low frequency. While a switching element 4 is O, the condenser 12 is charged via the rectifier 1, the switching element 4, the inductor 14, the diode 13, the condenser 12, and the rectifier 1. While a switching element 5 is ON, the condenser 9 is charged in the same way. They are charged with high frequency corresponding to the switching frequency of the switching elements 4, 5.

On the other hand, during the period when the switching element (4) is on, the capacitor a3 is connected to the rectifier (1) - switching element (4) - inductor Q4) - diode (13 - capacitor 2 - rectifier (1)). During the period when the switching element (5) is on, the capacitor (9) is similarly charged.These charges are carried out by the switching element (4), (
Since it matches the switching frequency of 5), it is charging at a high frequency of several KHz to several tens of KHz. Therefore, the charging current of capacitor (9), Q3 is as shown in Fig. 2 (Q).
