Implementation of Hysteresis Current Control for Single-Phase Grid Connected Inverter

This paper describes a control method for single- phase grid-connected inverter system for distributed generation application. Single-band Hysteresis Current Controller is applied as the control method. The control algorithm is implemented in digital signal processor (DSP) TMS320F2812. The control method provides robust current regulation and achieve unity power factor. Simulation and experimental results are provided to demonstrate the effectiveness of the design.
