Despite recent advances in solid-state controls for electric cars, chopperinduced problems still exist: Commutation and ac losses are significantly high, the chopping action induces losses within the power source, and large ripple components in the chopper output cause increased rms losses at the motor. the author's dual chopper, two conventional choppers in parallel, reduces these problems. the duty cycle generated by the firing circuit is feedback controlled so that the load current remains proportional to control output.
