Abstract

Pulse width Modulated (PWM) control technique for an a-c choppers using harmonic
elimination method is proposed. The firing switching instants of a-c chopper for the
proposed technique is derived theoretically. By using a microprocessor as a controller,
makes it possible to store the firing switching instants time as a look-up table for different
load voltage values. Two MOSFET's are used as an a-c chopper. Experimental results
verifying the simulation analysis of the a-c chopper fed static (R-L) load and dynamic load
(1-ph. induction motor). The proposed strategy is low cost, simplified, and control
effective.
