Claims (1)
- 交流,直流の順・逆変換機能を有し、交流電源から受電された交流電力を直流電力に変換するPWM型の整流器と、上記整流器から供給される上記直流電力を交流電力に変換して所定の交流負荷に与えるインバータとを含む電力変換装置において、
上記整流器と上記インバータとの間の直流回路部に直接的に接続され、上記整流器もしくは上記インバータを介して蓄電される複数の直列に接続された電気二重層キャパシタセルを含む電気二重層キャパシタと、
上記交流負荷の運転指令に基づいて上記整流器および上記インバータを制御して上記電気二重層キャパシタの充放電を制御する制御部と、
上記電気二重層キャパシタセルの各々に並列に接続され、上記電気二重層キャパシタセルが所定の満充電電圧となった時点で充電電流をバイパスする複数の並列モニタを含む電圧初期化手段とを備え、
上記制御部は、上記電気二重層キャパシタに対して、上記交流負荷を適正に駆動するうえで上記インバータが必要とする電圧よりも高い所定の許容最低電圧値を設定し、上記インバータへの放電によって上記電気二重層キャパシタの電圧が上記許容最低電圧値までに低下した場合には、上記整流器にて上記交流電力から変換される直流電力の出力電圧を高めて直接上記インバータに給電して上記電気二重層キャパシタからの放電を停止するとともに、上記電圧初期化手段から上記電気二重層キャパシタの満充電状態を示す満充電信号を受信した場合には、上記整流器を制御し上記インバータからの回生電力を上記整流器を介して上記交流電源に回生して上記電気二重層キャパシタに対する充電を停止することを特徴とする電気二重層キャパシタを用いた電力変換装置。
