- 1. A method of controlling an electric power source apparatus comprising an electric power converter circuit having on-off controllable switch elements to convert an output of an electric power source into predetermined DC or AC output by switching said switch elements and a pair of load connection terminals across which is applied an output voltage of said electric power converter circuit while said electric power source apparatus is allowed to be driven in the condition that a voltage from another electric power source is allowed to be applied across said load connection terminals and comprising the steps of;detecting waveform data of said voltage across said load connection terminals in the condition that said output of said electric power converter circuit is stopped during a period required for detecting said waveform data to specify said waveform of said voltage across said load connection terminals; and controlling said switch elements so that said waveform of said voltage applied across said load connection terminals from said electric power converter circuit is consistent with a waveform specified by said waveform data stored by said voltage waveform detection means.
