Abstract

This paper investigates the SVPWM switching scheme for the dual two-level inverter for generating three-level space vector. The decoupled SVPWM is employed for the dual-inverter scheme in order to realize the reference voltage vector. This paper identifies the error voltage vectors in the dual-inverter scheme by identifying the error voltage vectors of the individual two-level inverters. This paper presents the analytical expression for the rms ripple current in the dual-inverter scheme. The current trajectory is theoretically estimated indirectly using the error voltage vectors in the dual-inverter scheme. The performance is studied analytically and compared with the simulations carried out using Matlab/SIMULINK and finally cross-verified by performing suitable experiments on a 1 kW open-end winding induction motor drive.
