N2 - Wireless power transmission (WPT) has great potential for charging electric vehicles. Constant voltage (CV) and constant current (CC) are two major types of battery charging modes. In this paper, we analyze the output characteristics of series–series (S‐S) topology and double capacitances and inductances–series (LCCL‐S) topology. Voltage gain variation is achieved in the LCCL‐S compensation structure without additional components, and the system is still kept in resonant condi-tion. A WPT experimental platform was also built and tested based on the theoretical analysis. When the load resistance is 300 Ω, a voltage gain of 0.7 or 2.22 is achieved for the LCCL‐S with a compen-sating inductor of 100 μH or 33 μH, respectively. The experimental results fit the theoretical analy-sis. The CC/CV output characteristics and efficiencies of S‐S and LCCL‐S topologies in a wide load resistance range are also demonstrated. Moreover, zero voltage switch (ZVS) is also implemented in both two systems.
