voltage 15 230 ४, 50 Hz. The delay angles of thyristors are 01 = 02 = a = 90°.
Find RMS output voltage, and the input power factor.

Draw the circuit diagram of a single-phase full-wave AC voltage controller
which uses only one thyristor, along with uncontrolled switching devices. Also
explain its operation. What is the main advantage of this circuit?

Draw the circuit diagram of a four-quadrant chopper. Sketch the corresponding
quadrant diagram and indicate the conducting devices on the diagram.

With neat circuit diagram and waveform, explain the working of a buck-boost
regulator.

Design filter inductance and capacitance of a buck- boost regulator.
