A unified PWM strategy for matrix converters and its dipolar PWM realization
The 2010 International Power Electronics Conference - ECCE ASIA -, 2010This paper proposes a unified algorithm for PWM strategies of matrix converters. A general form of the modulation functions for the matrix converter is derived based on the geometric transformation approach. The research results reveal that each allowable modulation matrix can be expressed as an indirect modulation.

Optimized total harmonics distortion PWM and multi-carries PWM: Comparison
2015 IEEE 5th International Conference on Power Engineering, Energy and Electrical Drives (POWERENG), 2015In this paper, the comparison between the optimized total harmonic distortions OTHD PWM and the traditional multi-carriers PWM is studied to generate high quality output spectrum in five level inverter. For the OTHPWM, the switching angles are computed by solving a non-linear equation using the differential evolution method.

A Novel ZCS-PWM Flyback Converter With a Simple ZCS-PWM Commutation Cell
IEEE Transactions on Industrial Electronics, 2008This paper proposes a novel zero-current-switching pulsewidth-modulation (ZCS-PWM) flyback dc/dc converter using a simple ZCS-PWM commutation cell. The main switch and auxiliary switch operate at ZCS turn-on and turn-off conditions, and all uncontrolled devices in the proposed converter operate at zero-voltage-switching (ZVS) turn-on and turn-off.

A simulation benchmark for selection of the PWM algorithms for a multilevel PWM matrix converter
2014 International Conference on Optimization of Electrical and Electronic Equipment (OPTIM), 2014This paper considers the conventional three-phase matrix converter operated with PWM techniques making use of all possible commutation vectors. The output phase voltage can see multiple voltage levels - hence the multilevel matrix converter name. The hardware set-up to achieve the matrix converter operation can be built of three 3-phase Current-Source ...

A Comparative Study of Sinusoidal PWM and Space Vector PWM of an Induction Machine
2019The inverter is a static converter that provides an AC voltage of adjustable amplitude and frequency from a DC voltage source. Any type of inverter (voltage or current) requires a control technique that depends on the type of machine to be controlled. Mainly, the standard performance makes it possible to evaluate and compare the different techniques of
