Analysis and design of DSP-based dual-loop controlled UPS inverters
Abstract: This paper presents a novel digital dual-loop control scheme of the PWM(Pulse width modulate) inverter. Deadbeat control technique are employed to enhance the performance. Half switching period delayed sampling and control timing strategy is used to improve the system dynamic response. Simulation and experimental results presented in the paper verified the validity of the proposed control scheme.
