Pulse width modulated voltage source inverters (PWM VSI) for uninterruptible power supply (UPS), parallel redundant system applications require fast acting inverter output current and voltage control. This paper describes a multivariable state feedback control technique for the design of the voltage regulator for a three-phase current controlled PWM VSI. The control method provides a fast response and robust control (insensitive to plant parameter variations) of the load voltage in the presence of load/line disturbances. The voltage regulator is operated in the rotating d-q frame in synchronism with the fundamental frequency. The state space model of the plant of the voltage regulator is developed in the d-q frame. The description and analysis of the voltage control method is presented. A simple procedure to design the voltage regulator has been outlined and digital simulations are carried out which demonstrate the excellent dynamic performance of the voltage control system
