Description
前記制御部には、前記交流電源の周波数またはその半分の周波数と前記三相インバータの出力周波数指令との偏差が所定値以内のときに、前記出力周波数指令を補正する動作を行うか否かを該三相インバータの出力電力値に基づいて決定する判別手段を備えたことを特徴とする。
Claims (1)
- 交流電源の三相交流電圧を入力とし、任意の周波数の単相交流電圧を出力する複数台の単位インバータを3組に分割し、その出力を各組毎に直列接続した一端それぞれを中性点に接続し、それぞれの他端から三相交流出力を得るように構成した三相インバータと、この三相インバータを所望の動作状態に制御する制御部とからなる電力変換装置において、
