This paper accords a novel 3-ϕ (three-phase) boost type Vienna rectifier for AC/DC power conversion. The proposed circuit topology is employed for the power conversion of AC into DC with the enhanced output voltage and reduced switching losses. It is a preferable front side conversion unit for AC power generated renewable energy systems and also for AC input fed DC applications. Vienna rectifier is adequate where a unidirectional power flow is essential in the system with high power density and low voltage stress across the switches. The AC to DC Vienna Rectifier provides approximately a unity PF (Power Factor), sinusoidal input current and low THD (Total Harmonic Distortion) at the supply side. In this paper, the Vienna Rectifier is engaged in the conversion of a 230V AC to 400V DC with 50% reduction of voltage stress across the switches. The SVPWM (Space Vector Pulse Width Modulation) controller based proposed circuit topology is designed for 1kW PMSG (Permanent Magnet Synchronous Generator) wind energy conversion system (WECS) in MATLAB/Simulink and results are validated. © 2017, International Journal of Renewable Energy Research.
