An advanced three phase five level PWM rectifier

2009 International Conference on Power Engineering, Energy and Electrical Drives, 2009
In this paper, authors propose an advanced five level rectifier which results from a series connection of two three level rectifiers. A topological optimization of this configuration leads to the proposed topology characterized by the use of only six power switches per phase.

Virtual flux based direct power control of three-phase PWM rectifiers

Conference Record of the 2000 IEEE Industry Applications Conference. Thirty-Fifth IAS Annual Meeting and World Conference on Industrial Applications of Electrical Energy (Cat. No.00CH37129), 2001
In this paper, direct power control (DPC) of three-phase pulsewidth-modulated rectifiers without line voltage sensors is presented. The new system is based on virtual flux (VF) estimation. Theoretical principles of this method are discussed. The steady-state and dynamic behavior of VF-DPC are presented that illustrate the operation and performance of ...

Synchronverter-based control strategies for three-phase PWM rectifiers

2012 7th IEEE Conference on Industrial Electronics and Applications (ICIEA), 2012
Current control and direct power control (DPC) are popular control strategies for PWM rectifiers. In this paper, two novel control strategies are proposed to operate a rectifier to mimic a synchronous motor. One is to directly control the power extracted from the source and the other is to control the output voltage.

Average current control of three-phase PWM boost rectifier

Proceedings of PESC '95 - Power Electronics Specialist Conference, 2002
Average current control of three-phase PWM boost rectifiers with three linear current compensators and six-step PWM is a very attractive solution for its simplicity. The performance of the closed-loop control depends on the compensator design. This paper presents a modeling, analysis and design procedure for the average current control scheme.

Harmonic minimization in a three-phase asymmetrical PWM rectifier

Proceedings of MELECON '94. Mediterranean Electrotechnical Conference, 2002
A new pulse-width modulation (PWM) method for a three-phase bridge rectifier developed here gives minimized low order harmonics. As a PWM rectifier, it offers better input and output characteristics than phase-controlled rectifiers. It has inherited the characteristics of the PWM rectifier such as having high power factor at the input with low harmonic

A three-phase three-switch two-level PWM rectifier

IEEE 34th Annual Conference on Power Electronics Specialist, 2003. PESC '03., 2004
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 Simulation of Three-Phase Voltage Source PWM Rectifier

2012 Asia-Pacific Power and Energy Engineering Conference, 2012
Three-phase PWM voltage rectifier (VSR) applies Pulse Width Modulation (PWM) technology, it can overcomes the drawbacks of the conventional rectifiers, and has higher power factor, lower harmonic current and rapid dynamic respond, so VSR used widespread.

Modeling and Stability Analysis of Three-Phase PWM Rectifier

2018 IEEE International Power Electronics and Application Conference and Exposition (PEAC), 2018
According to the instantaneous active power balance, the small-signal mathematical model from active current to dc-side bus voltage is proposed. When the rectifier operates in the rectification mode, it has a right-half-plane (RHP) zero and exhibits a non-minimum phase feature which causes a phase lag and affects system stability.
