Abstract:
1. An electric power converter of a switched capacitance type, comprising: a first input-output part; an inductor connected with either a positive electrode side or a negative electrode side of the first input-output part; a plurality of switches; a plurality of capacitors which are connected in series; a second input-output part connected with the plurality of capacitors; and a control circuit adapted to make ON/OFF control of the plurality of switches in accordance with mode of operation to selectively use the inductor and the plurality of capacitors to provide any operation out of step-up, step-down, regeneration, and electrical continuity, wherein the control circuit is adapted to control the mode of operation of two of the switches out of the plurality of switches in Modes Mode wherein during the Mode during Mode during Mode
