Electric power unit with early auxiliary capacitor charging

摘要: The present invention relates to an electric power unit with a condenser input type rectification circuit which converts alternating current source direct voltage, and more particularly, for inverter-controlled refrigerators. An according the feeds load ( 7 ), comprises 1 bridge-type 2 ) having from consisting of bridge-connected diodes (D , D 3 4 auxiliary capacitor connected in parallel output series reactor diode 5 between one so as flow forward direction, smoothing 6 ). Moreover, is constituted first 42 second 43 capacity made variable through controlling connection by switching means 44 accordance change running or environment where used.
