In this paper, the design method of inverter instantaneous voltage-current PI controller based on pole-as-signment is proposed and mathematical models of a single-phase PWM inverter are established. The instantaneous capaci-tor-current feedback loop control strategy is compared with the instantaneous inductance-current feedback loop control strategy. Simulation results indicate that the instantaneous capacitor-current and voltage dual-loop feedback control strategy has high performance of output voltage
