This paper presents a 55kW three-phase soft-switching inverter for hybrid electric vehicle drives at high temperature conditions. Highly integrated soft-switching modules have been employed to achieve switching loss as well as conduction loss reduction. Detailed experimental evaluations of inverter efficiency have been conducted through both inductive load and motor-dynamometer load at coolant temperatures...
This paper presents a high efficiency three-phase soft-switching inverter for electric vehicle drives application. A 12 kW three-phase soft-switching inverter using CoolMOS as the main device and IGBT as the auxiliary device has been designed and fabricated. The electric vehicle drive test system has been assembled with soft-switching inverter, induction motor and dynamometer. The soft-switching inverter...
High temperature inverter involves thermal management, packaging, semiconductor device, switching circuit, and control circuitry. This paper is to focus on the drivetrain inverter design consideration for electric and hybrid electric vehicles. Basic structure and switching characteristics of different insulated-gate-bipolar-transistors (IGBTs) will be discussed. The use of silicon carbide Schottky...
