Dc power source device
专利汇可以提供Dc power source device专利检索，专利查询，专利分析的服务。并且PURPOSE:To reduce the switching loss of a DC power source device, by connecting selectively to load first and second capacitors which are alternately charged every half cycle through a switching element and a series reactor. CONSTITUTION:When a switch 3 is closed, resonance current passes through a power source 1, a diode 11, the first capacitor 13, the switch 3 and a reactor 10, and the first capacitor 13 is charged. On the other hand, during this time, the second capacitor 14 discharges to a load 2 the AC charge which has been charged during the previous half cycle through a switch 15. When charging of the first capacitor 13 is completed, the switch 3 becomes OFF, and in this case, since current is not passing the switch 3, switching loss does not occur. During the next half cycle, the same motion is repeated provided the situations of the first and second capacitors are inverted.，下面是Dc power source device专利的具体信息内容。
