Abstract

This paper presents a nine-switch 3- level inverter used as software for all-electric powered vehicle (EV) and hybrid-electric powered vehicle (HEV) motor drives. The proposed 3-level inverter is composed of a three-section-level inverter and three bi-directional strength switches. The proposed inverter overcomes a few shortcomings of 2- level inverters, including high switching frequency, excessive dv/dt and electromagnetic interference (EMI). The proposed inverter also reduces the wide variety of electricity switches from twelve to nine in comparison with conventional three-level inverters. Fewer switches lessen system value and improve system reliability. The proposed three-level inverter is suitable for low voltage applications due to the fact the voltage strain across a part of energy switches on this circuit is full of the DC bus voltage. Losses of the proposed inverter are analyzed and compared with other two inverters. The basic precept and control scheme of the proposed 3-level inverter are brought. Analytical, simulation, and experimental results display the superiority of the proposed 3-level inverter for electric vehicle applications.
