前記低電圧DC電源によって電力供給され、前記Hブリッジ(H)に電流を供給して前記容量性負荷(C L )を前記DC電源電圧よりも高い電圧に充電するように構成されたコンバータと、
前記コンバータと前記Hブリッジ(H)との間に直列に配置され、電流が前記充電された容量性負荷(C L )から逆流するのを防止するダイオード(D)と、
前記ダイオード(D)よりも下流側に前記Hブリッジ(H)と並列に設けられたコンデンサ(C S )とを備え、
前記Hブリッジ(H)のスイッチング素子(S A 、S B 、S C 、S D )は、第1の条件では、一方のリムの前記第1のスイッチング素子(S A )および他方のリムの前記第2のスイッチング素子(S B )が導通して、前記コンバータから前記容量性負荷(C L )へと電流を一方向に供給し、第2の条件では、前記リムの残りの2つのスイッチング素子(S C 、S D )が導通して、前記コンバータから前記容量性負荷(C L )へと電流を反対方向に供給するように、交互に制御され、
前記ダイオード(D)の下流側に前記Hブリッジ(H)と並列に設けられた容量の全容量値は、前記容量性負荷(C L )の容量値の10%と50%の間の大きさであり、
使用中、前記容量性負荷(C L )が負荷電圧(V L )まで充電された状態において前記Hブリッジ(H)が切り換えられるように構成されたことを特徴とする電子回路。 - 前記コンバータは、直列に配置された誘導性素子(L)および出力スイッチング素子(S)を有し、
前記出力スイッチング素子(S)は、使用中、第1の状態と第2の状態との間で交番するように構成され、それにより、前記第1の状態では、前記誘導性素子(L)および前記出力スイッチング素子(S)を介して電流路が得られ、前記電流路は、前記出力スイッチング素子(S)が前記第1の状態から前記第2の状態に変化するとき、前記誘導性素子(L)が前記容量性負荷(C L )を充電するための電圧を前記回路の出力において生成するように、前記第2の状態で遮断される請求項1に記載の電子回路。
