Abstract

Abstract Translated from Japanese (57)【要約】 【課題】 素子の焼損を防止しかつエネルギ回生可能な 双方向DC−DCコンバータを提供する。 【解決手段】 DC−DCコンバータ2は、バッテリ1 と、コンデンサ4が並列接続された負荷3と、の間に設 けら、バッテリ1に並列接続されるNチャンネルMOS FETであるQ1とQ2とが直列接続された第1直列回 路と、負荷3に並列接続されるNチャンネルMOSFE TであるQ3とQ4とが直列接続された第2直列回路 と、Q1とQ2との接続点とQ3とQ4との接続点との 間に設けられたインダクタンスLと、バッテリ1のエネ ルギを負荷3およびコンデンサ4に供給し、コンデンサ 4に蓄えられたエネルギをバッテリ1に回生するよう に、Q1、Q2、Q3およびQ4の各ゲートを制御する 制御手段と、を備える。 (57) [Problem] To provide a bidirectional DC-DC converter capable of preventing element burnout and recovering energy. A DC-DC converter includes a battery. And a load 3 connected in parallel with the capacitor 4, and an N-channel MOS connected in parallel with the battery 1. A first series circuit in which FETs Q1 and Q2 are connected in series; and an N-channel MOSFET connected in parallel to a load 3. A second series circuit in which Q3 and Q4, which are T, are connected in series, an inductance L provided between a connection point between Q1 and Q2 and a connection point between Q3 and Q4, and the energy of the battery 1 as a load. And control means for controlling the gates of Q1, Q2, Q3 and Q4 so as to supply the energy to the battery 3 and the capacitor 4 and regenerate the energy stored in the capacitor 4 to the battery 1.
