Document Type and Number:
Japanese Patent JP2015080360
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a general-purpose, low-cost and compact power control device for system interconnecting a plurality of types of distribution power supplies, with reduced power consumption and suppressed reduction of power generation efficiency.SOLUTION: A power control device 1 includes a control unit 10 having a plurality of control signal generator units 11, 12 for generating control signals to control transformer units (41, 42, 43) to step up or down power from DC power supplies (51, 52, 60). When the DC power supplies (51, 52, 60) are power generation sources, the control unit 10 controls one of the control signal generator units 11, 12 per power generation source to generate a control signal, whereas when the DC power supplies (51, 52, 60) are storage batteries, the control unit 10 controls two of the control signal generator units 11, 12 per storage battery to generate each control signal.
