This paper describes the application of a single-stage unity-power-factor buck-type pulsewidth modulation (PWM) rectifier to medium- and high-power variable-speed dc motor drives. The advantages of the developed system are low harmonic distortion in ac supply currents (complying with IEEE Std. 519 and IEC 555), nearly unity power factor over a wide operating shaft speed range, and nearly level armature current and voltage waveforms. These properties of output voltage and current quantities of the converter eliminate entirely any failure risk in current commutation even for oldest motor designs, and further motor problems such as accelerated aging in motor insulation, and mechanical failure due to circulating bearing currents. The design criteria and operating features and characteristics of the buck-type PWM rectifier employed in a unity-power-factor dc motor drive. are discussed in the paper. The performance of the resulting system has been tested on 25-65-kW 100-150-A 10-20-kHz dc motor drives, used in various processes of an iron and steel plant.

A three phase all sic PWM rectifier for industry applications Yolaçan, Cem; Ermiş, Muammer; Department of Electrical and Electronics Engineering (2019) In this thesis work, a three phase PWM Rectifier for industry applications will be designed by using SiC Power MOSFETs and its laboratory prototype will then be implemented. The topology of the PWM rectifier is the three phase full bridge topology to convert three phase 400 V AC line-to-line voltage to desirable voltage levels between 500V and 1000V. The PWM Rectifier has the capability of permitting the flow of active power in both directions. The new technology SiC Power MOSFETs can operate at higher freq...
A Self-Powered and Efficient Rectifier for Electromagnetic Energy Harvesters Ulusan, Hasan; Zorlu, Ozge; Muhtaroglu, Ali; Külah, Haluk (2014-11-05) This paper presents an interface circuit for efficient rectification of voltages from electromagnetic (EM) energy harvesters operating with very low vibration frequencies. The interface utilizes a dual-rail AC/DC doubler which benefits from the full cycle of the input AC voltage, and minimizes the forward bias voltage drop with an active diode structure. The active diodes are powered through an AC/DC quadrupler with diode connected (passive) transistors. The interface system has been validated to drive 22 m...

A Near-State PWM Method With Reduced Switching Losses and Reduced Common-Mode Voltage for Three-Phase Voltage Source Inverters Uen, Emre; Hava, Ahmet Masum (2009-03-01) The near-state pulsewidth modulation (NSPWM) method, which reduces the common-mode voltage/current, is proposed for three-phase pulsewidth modulation (PWM) inverter drives. The method is described, its optimal voltage vectors are found, and the sequence that these vectors are applied is determined. Its voltage linearity and de bus and ac output PWM current ripple characteristics are studied. Its output line-to-line voltage pattern is carefully studied with regard to switching transients that may cause overv...
A CMOS High Frequency Pulse Width Modulation Integrated Circuit Sahin, Osman Ulas; Kocer, Fatih (2016-08-05) In this work, a high frequency pulse width modulation (PWM) integrated circuit (IC) designed and implemented in a commercial 0.35 mu m CMOS process is presented. Based on natural sampling method, the proposed PWM IC can generate both a PWM signal and its inverse for arbitrary frequencies up to 5 MHz. The PWM frequency can he adjusted via an external clock and an off-chip capacitor. The duty cycle of the PWM signal can be linearly varied from 5% to 95% by changing the input signal. Thanks to its analog trian...
