A modular pulse-width modulation (PWM) power amplifier parallelable up to 47-KW peak is being used in magnetic resonance imaging (MRI), dc servo, audio, and other electromagnetic applications. Each of two independent half bridges in a module contains its own output filters and a multiple loop feedback system that equalizes power sharing, damps load ...

This chapter focuses on the control of single-phase and three-phase voltage-source inverters that are widely used for the conversion of AC electrical energy. Pulse-width modulation is discussed as a means of generating reference voltages based on inverter discrete states.

A second-order PWM-in/PWM-out class-D audio amplifier
IMA Journal of Applied Mathematics, 2011Class-D audio amplifiers convert an audio signal into a high-frequency square wave whose switching times are modulated according to that audio signal. Thus, they operate using so-called pulse-width modulation. When the high-frequency components of the output square wave are removed by filtering, the remaining lower frequency components can reproduce ...

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 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

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 ...
