A Single-Stage Square Wave Buck-Boost Inverter

Abstract:

This paper proposed a novel single-stage square wave buck-boost inverter (SWBBI). The proposed inverter is designed by using dual buck-boost converters. The input DC voltage of the proposed inverter can be either stepped-down or stepped-up in square output voltage waveform depending on the duty-cycle applied for each buck-boost converter. This characteristic is not found in conventional voltage source inverter where the output voltage is always lower than the input DC voltage. The proposed inverter is analyzed by a series of simulations using MATLAB/Simulink as well as experiments by using different values of duty-cycle. A conclusion about the feasibility of the proposed inverter is given by comparing the simulation and experimental results.
