Modeling of diode clamped inverter using SPWM technique

2017 International Conference on Green Energy Conversion Systems (GECS), 2017
Certainly many applications in industrial field have begun to require nowadays high power. However some industrial appliances require for their operation medium or low power. So using a high power source for all types of loads may be a benefic solution to some motors, while it makes damage for other loads.

An adaptive SPWM technique for cascaded multilevel converters

2015 IEEE Energy Conversion Congress and Exposition (ECCE), 2015
An adaptive carrier based sinusoidal pulse width modulation (SPWM) technique for cascaded h-bridge (CHB) multilevel converters is presented in this paper. The proposed technique enables the CHB topology to provide a symmetrical ac voltage from a set of time-variant input dc source voltages. Two alternative approaches, namely the single-carrier and dual-

Harmonic Analysis of SPWM Wave Generated PWM Output

2006 6th World Congress on Intelligent Control and Automation, 2006
The area equivalent principle is simple to generate sinusoidal pulse width modulation (SPWM) waves. The SPWM waves that are generated by output of pulse width modulation (PWM) in single-chip microcomputer or digital signal processor (DSP) are analyzed harmoniously. In the SPWM waves there are PWM waves of same duty ratio per small equal time. There are

Design of SPWM based three phase inverter model

2018 Technologies for Smart-City Energy Security and Power (ICSESP), 2018
This paper presents modeling of a gate pulse triggered three phase 180° voltage source inverter or VSI model supplying nonlinear loads with its output voltage and current waveforms. A two level pulse width modulation or PWM generator and a filter circuit has been proposed here for reduction of total harmonic distortion or THD of current and voltage ...

Design of a Multilevel Inverter Using SPWM Technique

2019
This paper proposes and examines a sinusoidal pulse width modulation (SPWM)-based single-phase diode clamped multilevel inverter for generation of multilevel output voltage. The SPWM signals and digital square pulses are generated using a single PWM module and I/O port of a PIC microcontroller.

A switching loss study in SPWM IGBT inverter

2008 IEEE 2nd International Power and Energy Conference, 2008
This work discusses an exact mathematical approach of calculating the IGBT turn-on, turn-off and on-state energy losses. Instantaneous voltage and current values are studied, linearized and employed to formulate the equations needed to calculate the IGBT switching loss.
