A single phase AC induction motor need to be controlled by
varying its input frequency. The supply frequency is a single phase
with 50 Hz and the input frequency to the motor is controlled to be
12.5 Hz. Design a Full-wave rectifier (Cycloconverter), show the
conversion of 5 cycles, and explain its operation. And show how the
output voltage of Cycloconverters can be controlled to get a
waveform shape near sine wave.

Draw the circuit for a three-phase full-bridge non-isolated
inverter. Describe how the converter works using switching
waveforms. Include a description of two different control
strategies using PWM and square-wave phase difference methods.
Clearly define the amplitude and frequency modulation indexes in
the PWM method. Discuss and calculate the rms phase and line
voltages when the DC input voltage is 400V.
