Abstract:
(EN) A full bridge circuit (10) is connected to a primary winding wire (n1) of a transformer (T1), and a full bridge circuit (20) is connected to a secondary winding wire (n2) of the transformer. The full bridge circuit (10) has: a first series circuit of switching elements (Q1-Q4); a second series circuit of switching elements (Q5-Q8); a first charge/discharge capacitor (Cf1) connected to a connection point between the switching elements (Q1, Q2) and a connection point between the switching elements (Q3, Q4); and a second charge/discharge capacitor (Cf2) connected to a connection point between the switching elements (Q5, 6), and a connection point between the switching elements (Q7, Q8). The full bridge circuit (10) operates in full bridge operation mode and/or half bridge operation mode. Consequently, a DC-DC converter, which is capable of constantly performing highly efficient operations even if a load fluctuation range is broad, is provided.
(FR) Selon la présente invention, un circuit en pont complet (10) est connecté à un fil d'enroulement primaire (n1) d'un transformateur (T1), et un circuit en pont complet (20) est connecté à un fil d'enroulement secondaire (n2) du transformateur. Le circuit en pont complet (10) comprend : un premier circuit série d'éléments de commutation (Q1-Q4) ; un deuxième circuit série d'éléments de commutation (Q5-Q8) ; un premier condensateur de charge/décharge (Cf1) connecté à un point de connexion entre les éléments de commutation (Q1, Q2) et à un point de connexion entre les éléments de commutation (Q3, Q4) ; et un deuxième condensateur de charge/décharge (Cf2) connecté à un point de connexion entre les éléments de commutation (Q5, Q6) et à un point de connexion entre les éléments de commutation (Q7, Q8). Le circuit en pont complet (10) fonctionne dans un mode de fonctionnement en pont complet et/ou un mode de fonctionnement en demi-pont. Par conséquent, un convertisseur continu-continu est obtenu qui est apte à effectuer constamment des opérations très efficaces même si une plage de fluctuation de charge est large.
(JA) トランス(T1)の1次巻線(n1)にフルブリッジ回路(10)を接続し、2次巻線(n2)にフルブリッジ回路(20)を接続する。フルブリッジ回路(10)は、スイッチング素子(Q1~Q4)の第1直列回路と、スイッチング素子(Q5~Q8)の第2直列回路と、スイッチング素子(Q1,Q2)の接続点と、スイッチング素子(Q3,Q4)の接続点とに接続された第1充放電コンデンサ(Cf1)と、スイッチング素子(Q5,6)の接続点と、スイッチング素子(Q7,Q8)の接続点とに接続された第2充放電コンデンサ(Cf2)とを有している。フルブリッジ回路(10)は、フルブリッジ動作モード又はハーフブリッジ動作モードの少なくとも一方で動作する。これにより、負荷変動範囲が広い場合であっても、常に高効率動作を行うことができるDC-DCコンバータを提供する。
