“…The current-source inverters (CSI) received a considerable attention by the researchers [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17] due to thier attractive features such as regeneration capability when supplied from a thyristor rectifier, and a better load voltage with low total harmonic distortion (THD). The CSI drive, as compared with the voltage source inverter (VSI) drive, has the ability to boost output voltages [3].…”

Two current-control strategies based on the sliding mode concept have been introduced for a single-phase currentsource inverter feeding a resistive load. The first strategy is based on forming a general switching function using the error variables of the inductor current and capacitor voltage. However, it is observed that this control strategy leads to a steady-state error in the capacitor voltage. In order to reduce this steady-state error, the second strategy using an additional integral term of the error variables in the switching function is proposed. It is observed that the additional integral term alleviates the steady-state error in the capacitor voltage. The existence conditions for stability are determined for both control strategies.Simulations and experiments are carried out to confirm the effectiveness of proposed control strategies.

“…Compared with VSI, CSI has many advantages, such as stable working conditions, direct control of output current, smooth the dc-link current, and faster dynamic response. The CSI is comparatively simpler, because CSI can buffer the output from grid voltage and generate a destined magnitude of current into the power grid, and achieves a high power factor with low-frequency switching [3], [4]. In addition, it has natural short-circuit protection capability.…”

This paper discusses a power analysis of the two-stage current source converter for single-phase grid-connected photovoltaic system applications. The aim of this research is to analyze the active powers of the converter. The proposed two stage power conversion topologies are consisting of a dc-dc converter and a single-phase current source inverter. This dc-dc converter operated with a phase shifted PWM technique, which produced three levels current on the output dc current, and current source inverter outputting a low frequency for injecting a sinusoidal current flowing into the power grid. Simulation results of the proposed system are demonstrate and discussed. As results, the proposed method is good conformation with the theoretical analysis in which the power factor and efficiency.

This paper presents a detailed analysis of a sevenlevel single-phase current source inverter for grid-connection systems. The aim of this research was to control high power factor operation, injecting a sinusoidal current flowing into the utility grid. The proposed two-stage power conversion strategies consisted of a dc-dc multilevel converter and a current source inverter, which operated with high switching and line frequency. A proposed topology is used to produce a seven-level current output with a phase-shifted PWM technique. A simple method is presented to improve the total harmonic distortion and power factor requirement. The feasibility of the proposed method was verified by simulation and experimental results.
