Boost Converter based 3-phase AC-AC Active Tracking Voltage Regulator Controlled by a Robust Hybrid Control Method

In this study, a switch-mode three-phase active tracking AC-AC voltage regulator based on the boost converter is proposed with moderate number of and passive elements used in topology. A robust hybrid control, where novel designed feedforward controller supports closed-loop PID controller, for control apart from similar studies literature. Active response reference output phase voltages augmented by method. Thus nearly close to sine-wave can be obtained, whether input AC are ideal pure sine or not. Also, modular structure topology enables independent each phase. Thus, supply balanced/unbalanced wye-connected loads single-phase wave achieved modularity regulator. Both experimental simulation test performed system. laboratory set-up 0-200 Vp (50 Hz), 0-300 voltages, 1.8 kW power. The results both tests verify boost-type regulator’s ability provide total harmonic distortion (THD) values under 5%.
