This study proposes a new power decoupling circuit applied to the single-phase current source converter (SCSC). Differing from the existing power decoupling technologies, the proposed power decoupling circuit could be viewed as a controlled voltage source in series with the DC inductor, and work with SCSC independently. That facilitates the separate design of the modulation schemes and the control algorithms for the power decoupling circuit and SCSC, and reduces the operation restrictions imposed by requirements. The fundamental principle of the proposed converter is analysed, and the voltage reference requirement for the buffer capacitor is investigated. To guarantee high input current quality of SCSC, a control method, where the input current is treated as a virtual control input, is proposed. Finally the effectiveness of this topology is verified by the simulations and experimental results.
