摘要
In this paper a simple and robust current control scheme for H-bridge grid-connected voltage source inverters is proposed. This scheme provides fast transient response quite similar to conventional hysteresis current control, while retaining switching frequency at a constant value over a line cycle. Switching times are predicted using simple mathematical relations and applied to the voltage source inverter. Furthermore, this scheme can be easily implemented using digital controllers. The steady state and transient performance are studied via simulation and experimental tests, which are in good agreement and validate the robustness and excellent performance of the proposed scheme.
