In inductive power transfer systems a smooth variation of input power can be achieved by using a controlled rectifier. The power can be changed by varying the fundamental amplitude of the primary and secondary voltages along with the phase angle between them. The paper shows how the input power is controlled and under what circumstances Zero Voltage Switching (ZVS) is lost on primary and secondary side of the system.
