Abstract(in Japanese) (See Japanese page)
Abstract(in English) PWM inverters have been applied recently to motors in various fields, being increasingly used in indoor equipment. Consequently, reduction of the motor noise generated by PWM inverter operation is a pressing problem. In the conventional PWM inverters (low noise type), noise is generated mainly by the output waveform distortion due to the "dead time". For the countermeasures, "dead time" compensation has been used, but complete compensation is difficult and it causes cost increase. A new control method, "AVSD-method" which eliminates the "dead time" essentially has been developed. It solved the problem completely, so that it has made possible development of PWM inverters with extremely small distortion in the output waveform at low cost.
