Abstract
Description
複数の絶縁電源を直流入力側で直列に接続して、高圧直流電源に接続することにより、絶縁電源1つあたりに印可される電圧を低くし、電力変換に使用するMOSFETの耐電圧を低くできるので汎用品のMOSFETを使用することができる。また、絶縁電源における電力変換に使用するMOSFETの制御回路、あるいは過電流保護回路等の制御回路電源を、起動時のみに低入力電源電圧(100V)を抵抗により電圧降下させて電源電圧とし、入力電源電圧が高い(700V)通常動作時は電圧降下用抵抗を使用せずに、トランスの3次巻線に発生する電圧を使用して制御回路電源としている。従って、制御回路電源を生成するための電圧降下用抵抗のワッテージを小さくすることが可能である。すなわち、電力変換装置の主回路電圧を、電力変換用のスイッチング素子駆動電圧(SW素子駆動回路16、17の電源電圧)に効率よく変換する
