Title:
ELECTRIC POWER CONVERSION SYSTEM
Document Type and Number:
Japanese Patent JP2016163475
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an electric power conversion system enabling a soft start so as to suppress the generation of an in-rush current or a voltage surge at triggering, without adding a new component.SOLUTION: An electric power conversion system, in which a step-up/down converter circuit 100 constructing a DC converter and a resonant converter circuit 200 as an insulation type LLC resonance converter are serially connected, executes a start-up processing in a control unit 20 by switching a first switching element 7 and a second switching element 8 of the insulation type resonance converter 200 at triggering, and starts a follow-up control to an output voltage target value after the start-up processing was started.SELECTED DRAWING: Figure 1
