Abstract
A current-sharing control strategy for paralleled multi-inverter systems using microprocessor-based robust control is presented in this paper. With an averaged current-sharing control (ACSC) strategy, the inverters are in parallel connection and each inverter has a voltage robust controller to achieve system stability and robustness, and a current robust controller to track the averaged inductor current of the inverters to achieve an equal current distribution. Simulation results and hardware measurements of a single-inverter system and a two-inverter system, and simulation results of a three-inverter system with linear and nonlinear loads have demonstrated the feasibility of the proposed control scheme in equal current distribution and fast regulation.
