| Abstract |
Active phase shifting method incorporates change in phase and amplitude of fundamental primary inverter output and secondary rectifier input voltages of a resonant DC/DC converter. This paper presents implementation of this method on four basic topologies of resonant tank configurations or compensation circuits of a resonant converter. Smooth variation of input power along with Zero Voltage Switching (ZVS) regions both on primary and secondary side have been observed for different configurations. Equations for input power as a function of the phase angles, switching frequency, input and output voltage amplitudes and the values of the reactive components have been derived. The results are verified with simulations of all the configurations and practical setup for one of the best configuration for IPT systems. |
