The operational principle and topology of multi-level current source converter as well as its main advantages are introduced. According to the characteristics of SVG (Static Var Generator), a model of multi-level current source SVG is built up and simulated with PSCAD/EMTDC. The influences of model parameters on the performance of SVG are discussed in the form of dynamic and steady waveforms of system voltage and current. Simulation results display the feasibility of proposed control strategy and the excellent performance of multi-level current source SVG.

This paper proposes the topological generated method, control method and circuit feature of the single primary winding current-fed full-bridge MIC. The MIC has only one primary winding. Compared with the traditional multiple primary winding current-fed MIC, it has simpler structure, more flexible control and can power the load simultaneously or individually. The Pulsating Current Source Cell in the converter is Boost type. The input current is continuous and it can prolong the usage age of PV cell and fuel cell. The single primary winding current-fed double-input full-bridge converter based on Boost converter is taken as an example to analyze its operation principle, control strategy. Simulation results are presented to verify the theoretical analysis

Current source converter is a variable structure system due to its switching nature, so that it can easily cause the output current waveform distortion and can not be accurately track the reference current. To solve the above problems, this paper proposes a new variable structure control strategy with fan-shaped sliding domain in the current source converter control system. In the control strategy, the paper deduces the switching surface and switching control law of SMVSC, and calculates the sliding existence domain based on the mathematical model of current source converter. Finally, the simulation results show that the control scheme can make current source converter have better output current waveform, fast tracking the reference current, and strong anti-interference ability. Therefore, the control scheme is correct, effective and feasible.
