Abstract
(EN)
A DC-DC converter, the loss of which can be reduced, is provided. Ein and C1 are connected in series. Q1 and Q2 are connected in series so that the direction of each reverse parallel diode is directed in the same direction. One terminal of the C1 on the side not connected to the Ein is connected to one terminal of the Q2 on the side not connected to the Q1. One terminal of the Ein on the side not connected to the C1 is connected to one terminal of the Q1 on the side not connected to the Q2. A coil (N1) of T is connected between the connection point between the Ein and the C1 and the connection point between the Q1 and the Q2. One of a pair of terminals of a coil (N2), having the same polarity as that of the terminal of the coil (N1) connected to the Ein, is connected through D1 to the connection point between the C1 and the Q2, and the other terminal is connected to the connection point between the Ein and the C1. A coil (N3) is connected through a rectifier circuit to a smoothing circuit. The direction of the D1 is determined such that when the Q1 is in a conductive state, energy can be transferred from the coil (N2) to the C1. The rectifier circuit applies a voltage having the same polarity to the smoothing circuit even when one of Q1 and Q2 is in a conductive state.

La présente invention concerne un convertisseur CC-CC, dont la perte peut être réduite. (Ein) et (C1) sont raccordés en série. (Q1) et (Q2) sont raccordés en série, de sorte que la direction de chaque diode parallèle inverse soit identique. Une borne de (C1) sur le côté qui n'est pas raccordé à (Ein) est raccordée à une borne de (Q2) du côté non relié à (Q1). Une borne de (Ein) sur le côté qui n'est pas raccordé à (C1) est raccordée à une borne de (Q1) du côté non relié à (Q2). Une bobine (N1) de (T) est raccordée entre le point de connexion entre (Ein) et (C1) et le point de connexion entre (Q1) et (Q2). Une borne d'une bobine (N2) parmi une paire, ayant la même polarité que celle de la borne de la bobine (N1) raccordée à (Ein), est raccordée via (D1) au point de raccordement entre (C1) et (Q2) et l'autre borne est raccordée au point de connexion entre (Ein) et (C1). Une bobine (N3) est raccordée via un circuit de rectification sur un circuit de lissage. La direction de (D1) est déterminée de sorte que lorsque (Q1) se trouve dans un état conducteur, l'énergie peut être transférée de la bobine (N2) à (C1). Le circuit de rectification applique une tension ayant la même polarité sur le circuit de lissage, même lorsque (Q1) et (Q2) se trouvent dans un état conducteur.

 損失を低減可能なDC-DCコンバータの提供を課題とする。EinとC1とが直列接続される。Q1とQ2とが、それぞれの逆並列ダイオードが同一方向を向くように直列接続される。C1のEinと非接続の端子と、Q2のQ1と非接続の端子とが接続される。EinのC1と非接続の端子と、Q1のQ2と非接続の端子とが接続される。EinとC1との接続点と、Q1とQ2との接続点との間にTの巻線N1が接続され、巻線N2の1対の端子のうち巻線N1のEinに接続される端子と同一の極性の端子がD1を介してC1とQ2との接続点に接続され、他方の端子がEinとC1との接続点に接続される。巻線N3は、整流回路を介して平滑回路に接続される。D1の向きは、Q1が導通状態の時巻線N2からC1にエネルギーを移送できるように定められる。整流回路は、Q1、Q2のどちらが導通状態の時も同一極性の電圧を平滑回路に印加する。
