Trapezoidal Amalgamated Rectangular PWM for Space Efficient High Boost Quadratic Inverter

This paper deals with a modular layout for the Space-Efficient High-Boost Quadratic Inverter (SEHBQI) which includes a trapezoidal Amalgamated Rectangular Pulse Width Modulation (TARPWM) control. The major objective of this proposed model is to overcome the drawback of the conventional multilevel inverters (MLIs) such as usage of large switches, sources, diodes and capacitors. The proposed SEHBQI uses can capable of generating nine level output with One DC source, two capacitors, eight switches and couple of diodes. The SEHBQI necessitates only few components compare to existing inverters. Furthermore, the quality of the output waveforms is improving by using unipolar multi-carrier modulation scheme with TARPWM control. The overall SEHBQI performance is assessed by MATLAB simulation test results in terms of low total harmonic distortion and high DC bus utilisation with various TARPWM control with variety of modulation index.
