Abstract
The authors describe a method for selecting pulse width modulation (PWM) patterns and a method for designing low-pass filters in large-capacity current source PWM power converters, to suppress higher harmonics flowing into the power supply. A test carried out on a 500 kVA PWM converter, employing the proposed methods, verified that they substantially decrease higher harmonics flowing into the power supply. The test also showed highly efficient converter characteristics with a supply power factor equaling almost 1.0
