    • PROBLEM TO BE SOLVED: To realize an SMR capable of avoiding problems such as difficulty of circuit parameter adjustment and many components which are caused by an analog circuit by controlling a PWM pulse control part not with an analog circuit but with software. SOLUTION: Data of each pulse width of a PWM pulse train corresponding to a rector current in the case of rated operation are obtained by previously performing simulation, and stored in a ROM table in a PWM pulse control part P1. Synchronously with an AC power source 1, the pulse width data are called in sequence in one cycle period of a half wave, and generate PWM pulses which are applied to the gate of an IGBT 7a. When a load changes, a correction coefficient is calculated on the basis of a previously obtained calculation formula of each pulse, and the PWM pulses are generated after correction is performed by multiplying each of the pulse width by the correction coefficient. As a result, power-factor improvement and rectification are enabled while the problems caused by an analog circuit are avoided.
