Modeling a Pluse-Width Modulation(PWM) Rectifier in 3D Space

Abstract

Power electronics pertains to a category of devices that convert electrical power from one form to another. Semiconductor devices act as switches in power electronics circuits, serving as the central components responsible for voltage regulation. Power electronics circuits strive to convert electrical energy from one form to another, from source to load, while minimizing cost, size, and weight as much as possible. The term “rectification” refers to the power circuit which alters the ac characteristic of the line electric power in order to supply “rectified” ac power with a dc value at the load side. The rectifier is utilized to convert alternating current (AC) voltage into direct current (DC) or low-frequency AC in order to power different load configurations. The AC mains are subjected to the injection of low order current harmonics by the Conventional Phase Controlled Rectifier. These harmonics necessitate the use of filtering components of considerable size for effective attenuation. The paper explores the simulation of the Converter through various PWM techniques, including space vector pulse width modulation and sinusoidal pulse width modulation.
