AC motor drives are widely used to control the speed
of conveyor systems, blower speeds, pump speeds, machine tool
speeds, and other applications that require variable speed with
variable torque. The complete system consists of an ac voltage input
that is put through a diode bridge rectifier to produce a dc output
which across a shunt capacitor, this will, in turn, feed the PWM
inverter.
