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...
متن کاملUnidirectional Three Phase High Power Factor Hybrid Rectifier
Abstract – Power factor corrected rectifiers are new tendency in development of power supplies. This paper presents a brief review of some high power rectifiers structures and provides an assessment of each analyzed technology. As contribution, a novel hybrid high power rectifier topology is proposed and analyzed. An active unidirectional three phase rectifier is associated in parallel with a t...
متن کاملTopic 7 Designing a Digital Telecom Rectifier
The design of a 1000-W universal AC input to 48-VDC output power supply is described. This power supply consists of an interleaved Power Factor Correction (PFC) stage and a phase shifted full bridge (PSFB) DC/DC converter, all controlled by a single UCD9501 DSP controller. The design steps leading to the development of the control effort for the DSP are outlined and compared to the equivalent s...
متن کاملPerformance Evaluation of Three Phase Scalar Controlled Pwm Rectifier Using Different Carrier and Modulating Signal
Power quality problems caused by significant increase of non-linear loads initiated intensive research in high power factor converters. Most of the modern power electronic systems like variable speed drives, DC power supplies and battery charging systems uses uncontrolled diode bridge rectifier. The uncontrolled rectifier system injects lot of harmonics in to the AC supply system there by reduc...
متن کاملTHD Mitigation in Line Currents of 6-Pulse Diode Bridge Rectifier Using the Delta-Wye Transformer as a Triplen Harmonic Filter
The uncontrolled three-phase bridge rectifier has the least line current distortion among six-pulse rectifiers; however, its total harmonic distortion (THD) of 31.08% is unacceptable as per the contemporary power quality standards. This paper seeks to address the issue by elimination of triplen harmonics in the line currents by providing a deltawye transformer at the ac interface i.e. between t...
