In this paper, a novel phase-shifted pulse width modulation (PS-PWM) automatic voltage regulator (AVR) with fast voltage control and reduced total harmonics is proposed. The novel PS-PWM AVR is made up of an AC/AC converter with reversible voltage control and a transformer for series voltage compensation. In the active rectifier, a proper switching operation is achieved without the problem of power factor correction. The AVR uses a fully digital controller, which is implemented by a fixed-point digital signal processor (DSP) TMS320F240 DSP-based board. Therefore, the proposed AVR gives high efficiency and reliability. It is also shown via some experimental results that the presented novel PS-PWM AVR gives good performance for high quality of the output voltage.
