Abstract:
(EN) The configurations of power conversion devices are complicated. A power conversion device according to the present invention is provided with a primary circuit, a secondary circuit, and a transformer. The primary circuit converts DC power into AC power and outputs the AC power. The secondary circuit converts the AC power into DC power. The transformer electrically isolates the primary circuit from the secondary circuit, transforms the voltage of the AC power output by the primary circuit, and outputs the voltage to the secondary circuit. The secondary circuit has a first capacitor, a second capacitor, a resistor, and a diode. The first capacitor removes ripple components of the DC power converted from the AC power. The second capacitor has a larger capacitance than the first capacitor, is connected in parallel with the first capacitor, and is charged with electrical power by the DC power converted from the AC power. The resistor is connected in series with the second capacitor. The diode is connected in series with the second capacitor and in parallel with the resistor and discharges electrical power charged in the second capacitor.
(FR) Selon la présente invention, les configurations de dispositifs de conversion de puissance sont compliquées. Un dispositif de conversion de puissance selon la présente invention est pourvu d'un circuit primaire, d'un circuit secondaire et d'un transformateur. Le circuit primaire convertit la puissance en courant continu en puissance en courant alternatif et transmet la puissance en courant alternatif. Le circuit secondaire convertit la puissance en courant alternatif en puissance en courant continu. Le transformateur isole électriquement le circuit primaire du circuit secondaire, transforme la tension de la puissance en courant alternatif transmise par le circuit primaire et transmet la tension au circuit secondaire. Le circuit secondaire comporte un premier condensateur, un second condensateur, une résistance et une diode. Le premier condensateur élimine des composantes d'ondulation de la puissance en courant continu convertie à partir de la puissance en courant alternatif. Le second condensateur présente une capacité supérieure à celle du premier condensateur, est raccordé en parallèle au premier condensateur, et est chargé en énergie électrique par la puissance en courant continu convertie à partir de la puissance en courant alternatif. La résistance est raccordée en série au second condensateur. La diode est raccordée en série au second condensateur et en parallèle à la résistance et évacue un courant électrique chargé dans le second condensateur.
(JA) 電力変換装置の構成が複雑化する。 電力変換装置は、一次回路と、二次回路と、変圧器とを備える。一次回路は、直流電力を交流電力に変換して出力する。二次回路は、交流電力を直流電力に変換する。変圧器は、一次回路と二次回路とを電気的に絶縁して、一次回路が出力した交流電力の電圧を変圧して二次回路に出力する。二次回路は、第1コンデンサと、第2コンデンサと、抵抗器と、ダイオードとを有する。第1コンデンサは、交流電力から変換された直流電力のリプル成分を除去する。第2コンデンサは、第1コンデンサよりも静電容量が大きく、第1コンデンサと並列に接続され、交流電力から変換された直流電力によって電力を充電する。抵抗器は、第2コンデンサと直列に接続されている。ダイオードは、第2コンデンサと直列に、かつ、抵抗器と並列に接続され、第2コンデンサに充電された電力を放電する。
