摘要：

In this paper, in order to make the design and control strategy of the secondary and primary sides simple, an additional capacitor with a semi-conductance switch is employed in the primary side to realize constant charging current (CC) or constant battery charging voltage (CV) without the need of regulating the input DC voltage of inverters, employing phase-shifted control in the primary side and DC regulation of the secondary side. In the CC mode, the compensation capacitor completely compensates the inductance of the primary coil while only a switch is needed to turn off/on the compensation capacitance to realize the CV mode. No sophisticate control strategy and simple feedback communication (mode change signal) are required in the proposed approach, so that the overall cost of IPT is low. The result of an experimental prototype demonstrated that the voltage and current of the proposed approach is slightly changing against the load resistance, while it still meets the requirement of battery charging. © 2016 Chin.
