International Journal of Power Electronics (IJPELEC), Vol. 12, No. 2, 2020

Abstract: This paper presents the design, analysis and digital implementation of space vector PWM-based various switching sequences for the Z-source inverter. Three main type of switching sequences have been taken, these are continuous switching sequence, basic bus clamping, and advanced bus clamping. Each of these sequences is designed in order to achieve symmetry in output line voltage. Two main control techniques, maximum boost, and maximum constant boost have been used to analyse each sequence in terms of switching transition per sample and duration of positive dc bus clamping. The novelty of the paper is the design of all switching sequence considering the conditions of symmetry and the implementation of advanced bus clamping techniques in the area of Z-source inverters. Simulation and experimental results have been presented to verify the design.
