PURPOSE:To reduce the size, the weight and the cost and to improve the efficiency by providing exclusive batteries respectively for the outputs of two sets of converters while furthermore arranging an inverter in one of the two sets of circuits connected with an AC load and producing a required AC voltage. CONSTITUTION:Required DC supply voltage for a DC load 4 and for floating charge of a battery 3 is fed exclusively by rectifying and smoothing the output voltage from the secondary winding W2 of a reactor L3W through a diode D3 and a capacitor C1. Required DC supply voltage of an inverter 6 for producing AC voltage necessary for an AC load 8 and for floating charge of a battery 5 is produced by rectifying and smoothing the output voltage from the ternary winding W3 of the reactor L3W through a diode D4 and a capacitor C2. The output voltages from the output windings W2, W3 of the reactor L3W are selected independently at optimal values corresponding to the voltage levels necessary for the AC and DC loads. |
