Vel Single-phase Zcs-pwm High Power Factor Boost Rectifier

This paper presents a novel single-phase high power factor PWM boost rectifier, featuring soft commutation of the active switches at zero-current (ZCS). It incorporates the most desirable properties of the conventional PWM and the softswitching resonant techniques. The input current shaping is achieved with average current mode control, and continuous inductor current mode. This new PWM convert...

Single Phase to Three Phase Drive System Using High Power Density Single Phase Pwm Rectifier with Active Ripple Energy Storage

The main objective of this project is single-phase to three-phase drive system composed of High power density PWM rectifiers with active ripple energy storage.The proposed topology permits to reduce the rectifier switch currents, the harmonic distortion at the input converter side and presents improvements on the fault tolerance characteristics. With the decrease in the number of switches, the ...

Performance analysis of three-phase PWM rectifiers for high power quality applications

In the past few years problems like harmonic pollution or waveform distortion became more important as the load nature changed. The typical linear loads have been progressively replaced by non-linear ones, where rectifier systems have a great importance. A wide variety of industrial applications such as variable speed drives and most of power electronics’ converters use uncontrolled rectifiers ...

A Novel Single-Phase ZCS-PWM High-Power-Factor Boost Rectifier

This paper presents a novel single-phase high-powerfactor (HPF) pulsewidth-modulated (PWM) boost rectifier featuring soft commutation of the active switches at zero current (ZC). It incorporates the most desirable properties of conventional PWM and soft-switching resonant techniques. The input current shaping is achieved with average current mode control and continuous inductor current mode. Th...
