Five-phase PWM current source rectifier

2013 7th IEEE GCC Conference and Exhibition (GCC), 2013
This paper introduces multiphase PWM current source rectifier (CSR). This rectifier is suitable for wind energy or micro turbine applications which have multiphase generators with no need for electric gear such as low frequency transformer. As a case study, medium voltage (MV) five-phase PWM current source rectifier (CSR) with controlled dc-link ...

Optimum digital control of PWM rectifiers

Proceedings of IECON'94 - 20th Annual Conference of IEEE Industrial Electronics, 2002
The paper presents an optimum digital control technique suitable for three-phase PWM rectifiers with a capacitive filter in the DC link. The proposed technique is based on a predictive current control loop, which does not need line voltage sensing and results in minimum RMS current absorption and unity power factor in any operating condition. Moreover,

Single-phase three-level PWM rectifier

Proceedings of the IEEE 1999 International Conference on Power Electronics and Drive Systems. PEDS'99 (Cat. No.99TH8475), 1999
This paper presents a new PWM control scheme for a single-phase three-level PWM rectifier to improve the power quality. A diode bridge with two power switches is adopted as a PFC circuit to achieve a high power factor and low harmonic distortion. The control scheme is based on a look-up table with hysteresis current controller (HCC).

Input filter design for PWM current-source rectifiers

Proceedings Eighth Annual Applied Power Electronics Conference and Exposition,, 1994
Pulse-width modulated (PWM) rectifiers are increasingly used because they allow the elimination of low-order harmonics, and therefore a reduction in input filter components. Filtering requirements for PWM current-source rectifiers are usually satisfied through the use of low-pass LC input filters.

Repetitive controlled three-phase reversible PWM rectifier

Proceedings of the 2000 American Control Conference. ACC (IEEE Cat. No.00CH36334), 2000
In this paper, a repetitive current control scheme for three-phase reversible PWM rectifier is proposed. The proposed control scheme is of typical dual-loop structure: inner AC current loop with plug-in repetitive plus feedback deadbeat controller, and outer DC voltage loop with PI controller.
