Abstract
A control method of a voltage to be applied to an electrifier includes the steps of measuring an integral value of an alternating waveform, and controlling an alternating current so that the integral value is constant in a predetermined time.
Claims15
A control method of a voltage to be applied to an electrifier, comprising the steps of:
- measuring an integral value of an alternating waveform;
- and
- controlling an alternating voltage so that the integral value is constant in a predetermined time.
A control method of a voltage to be applied to an electrifier, comprising the steps of:
- measuring an integral value of an alternating waveform;
- detecting a peak value of the alternating waveform;
- calculating an area of the alternating waveform from a detected peak value;
- and
- controlling an alternating voltage so that a difference between the integral value and the area becomes constant.

A control method of a voltage to be applied to an electrifier, comprising the steps of:
- applying an alternating voltage having a peak to peak voltage lower than twice a discharge start voltage to the electrifier and measuring a current supplied at this time;
- applying an alternating voltage having a peak to peak voltage not lower than twice the discharge start voltage to the electrifier and measuring a current supplied at this time;
- and
- determining a peak to peak voltage of an alternating voltage to be applied to said electrifier at an electrifying time on the basis of a measured alternating current value.
