Abstract: Among the source side converters with high frequency output capability, inductor-capacitor-inductor（LCL） resonant converter is a kind of load independent current source in the given working condition. However, the component tolerance and the outside perturbations make it difficult to maintain the constant output current. This paper proposed a new LCL resonant converter based on switched-controlled capacitor（SCC） structure. The proposed inverter can provide a controllable current output with the easy control strategy. In specific, the regulation of the duty cycle D changes the equivalent resonant capacitance, and the change of resonant frequency can further adjust the output current gain H against parameter tolerance and outside perturbations. The working principles and operational cycles of the proposed SCC circuit are examined in detail. The relations of the duty ratio to equivalent capacitance and duty cycle to output current gain H are demonstrated as well. Lastly, the simulation model and experiment prototype are implemented with the rated output power. The results of the experiment and simulation show that the proposed resonant converter provides the improved performance of constant current with the higher conversion efficiency.
