Simulation of SPWM based Z-Source Inverter
IOSR Journal of Electrical and Electronics Engineering, 2013 This paper presents a single stage Z-source inverter (ZSI) that can either buck or boost the ac output voltage from a DC supply. This topology overcomes the short comings of the where the output ac voltage is either less or more than the input dc voltage.

Simulation of SPWM Control Method for UPS System
International Journal of Computer Applications, 2014 paper deals with the analysis of implementing Sinusoidal Pulse Width Modulation (SPWM) controlling strategy in three phase Uninterruptible Power Supply (UPS) system operating under highly nonlinear load. The conventional type of controller is not enough to reduce harmonics in the system under highly nonlinear load in high power system.

Performance Improvement of Single Phase Inverter using SPWM
IOP Conference Series: Materials Science and Engineering, 2017 This paper concentrates on modelling and simulation of single phase inverter as a frequency changer modulated by Pulse Width Modulation (PWM). An inverter is a circuit that converts DC sources to AC sources. Pulse Width Modulation is a method that utilization as an approach to abatement add up to harmonic distortion in inverter circuit.
