Abstract

A novel control strategy for single-phase current source inverters connected to an AC grid is proposed in this paper. The control strategy aims to inject maximum power to the grid under transient and steady state-conditions by the tracking of sinusoidal references. The paper presents the modeling and the design of the control strategy based on the exact linearization of the inverter model. Results are obtained by computational simulation and validated experimentally. By using error performance indexes in the analysis of the results, it is demonstrated that the proposed controllers achieve correct tracking of the sinusoidal reference while keeping a low switching frequency, which helps to minimize the commutation losses.
