Abstract

A pulse with modulation(PWM) that keeps a constant angle of dwell and adjusts duty ratio is a good method for speed control of SRM. And a method of one pulse control is proper to operate on range of high speed in SRM for a good energy efficiency. Because PWM method is more safety than one pulse method, conversion of those is best choice according the speed range. So, some algorithm is demanded for smooth conversion of the mode for speed control. This paper presents a factor for conversion that satisfies the conversion of control mode between PWM and one pulse method smoothly. The factor can be determined from estimation of torque. And the factor is proper at the variable range of conversion and shows the adaptive conversion characteristic than constant factor applied.
