A Comparative Study of Single-switch, Three-phase, High-power-factor Rectifiers
نویسندگان
چکیده
Three three-phase, single-switch, high-powerfactor rectifier implementations were evaluated on a comparative basis. Specifically, the discontinuousconduction-mode boost rectifier with a 5-harmonic-trap filter, the discontinuous-conduction-mode boost rectifier with a harmonic-injection circuit, and the multi-resonant, zero-current-switching buck rectifier were compared with respect to their efficiencies, compliance with the IEC555-2 specifications, volumes, weights, and costs. The comparisons were done for the three-phase, line-to-line input voltage of 380 Vrms ± 20% and for 0 6 kW outputpower range.

Design and Simulation of a New DC Power Supply Based on Dual Bridge Matrix Converter
A conventional high power DC power supply systems consist of a three-phase diode rectifier followed by a high frequency converter to supply loads at regulated DC voltage. These rectifiers draw significant harmonic currents from the utility, resulting in poor input power factor. In this paper, a DC power supply based on dual-bridge matrix converter (DBMC) with reduced number of switches is p...

Several new schemes for constructing 3 lowharmonic rectifiers are introduced here. These 3 ac–dc topologies are derived from parent dc–dc converter topologies. With a single active switch featuring the zero-voltage switching (ZVS) property in addition to the diode-rectifier bridge, the rectifiers are capable of naturally drawing approximately sinusoidal input-current waveforms at nearly unity p...

Several basic classes of three-phase high-quality rectifiers are described. Both single-switch and six-switch three-phase rectifier topologies can be derived from parent dc-dc converters. Single-switch rectifiers are compared with the basic six-switch PWM rectifiers performing similar power conversion functions, using the measures of total semiconductor stress and active semiconductor utilizati...
متن کاملNew Single-Switch Three-Phase High-Power-Factor Rectifiers Using Multiresonant Zero-Current Switching
A new family of single-switch three-phase highpower-factor rectifiers, which have continuous input and output currents, is introduced. By using a multiresonant scheme, the transistor operates with zero-current switching (ZCS), and the diodes operate with zero-voltage switching (ZVS). These multiresonant rectifiers with a single transistor are capable of drawing a higher quality input-current wa...
متن کاملA Single Transistor Three Phase Resonant Switch for High Quality Rectification
Existing 34, ac-dc low-harmonic rectiifiers are costly and require complex control schemes to minimize input current harmonics. Introduced here are three new classes of low cost 34, acdc high power factorllow harmonic controlled rectifiers. These are derived from parent dc-dc convrter topologies containing boost-type inputs, buck-type inputs and qwsi resonant zero-current-switch (ZCS) buck-type...
