Abstract :
This paper presents a new topology for a high power factor three-phase PWM rectifier system, without a neutral wire, with output voltage control and high efficiency. The control is simple and was implemented using commercial single phase modulators with independent current loops and a voltage loop. The power circuit is also very simple, permitting the use of low cost power devices. A mathematical analysis for the converter is presented, including the determination of all the power devices, the current and voltage transfer functions and a project procedure. Finally, results obtained through digital simulations and the experimental results obtained from a 6 kW prototype are presented.
