Title:
POWER CIRCUIT
Document Type and Number:
Japanese Patent JP3628348
Kind Code:
B2
Abstract:
PURPOSE: To reduce the interaction among respective power circuits of the power circuit consisting of a plurality power circuits.
CONSTITUTION: A DC/DC converter is constituted by connecting 1st-5th DC/DC converting circuits in parallel. In the DC/DC converting circuits, currents flows to corresponding inductors L11-L15 and are accumulated in capacitors C1-C5 when switches SW1-SW5 are closed, but voltage are outputted when they are opened. The switches SW1-SW5 are so controlled that at least one of them is closed. Further, the switches SW1-SW5 are so controlled that switches SW of mutually adjacent DC/DC converting circuits are not closed at the same time.
