摘要

The incorporation of renewable energy sources (RES) into power grids presents a challenge due to their intrinsic DC characteristics. Inverters play a critical role in converting this DC power to grid-compatible AC. This paper explores the modeling and design of a three-phase bidirectional AC-DC inverter with an adaptive PI controller. The proposed system utilizes a well-established sinusoidal pulse width modulation (SPWM) vector decoupling control method. With this method, active and reactive power can be independently regulated. Ensuring stable output voltage from the rectifier. In addition, the bidirectional property provides a bi-directional current transfer between DC and AC grids with preserving unity power factor. Simulations on a 10 kW prototype developed in MATLAB/Simulink validate the effectiveness of the proposed system.
