【実用新案登録請求の範囲】[Scope of utility model registration request] サイリスタ順逆変換装置により直流を介して可変周波数
の交流を発生して、電動機を始動するもので、逆変換装
置に変圧器を備え、始動初期には変圧器をバイパスして
始動するものにおいて、上記変圧器をバイパスして始動
する期間は専用の逆変換用変換器を使用する構成とした
ことを特徴とするサイリスタ始動装置。A thyristor forward/inverter converter generates variable frequency alternating current via direct current to start the motor, and the inverter is equipped with a transformer and starts by bypassing the transformer in the initial stage of startup. A thyristor starting device characterized in that a dedicated inverse converter is used during a starting period when the transformer is bypassed.
