Abstract

One of current challenges in high-density electric vehicles (EVs) is the efficient thermal control of power converters and the reliable management of power flows in motoring/breaking mode for the battery bank. In this line, this paper presents an Active Thermal Control (ATC) scheme to regulate thermal stress in Gallium Nitride High Electron Mobility Transistors (GaN HEMTs) devices of a three-level bidirectional buck-boost DC-DC converter (TLBBC) as a power interface between battery and motor inverter. The TLBBC is designed to operate at a rated power of 20 kW as part of a modular system, by using parallel GaN devices. Proposed control schemes are implemented using systematic linear control design. Finally, the system is simulated and tested for a Mission Profile-Oriented (MPO) based on Highway Fuel Economy Test (HWFET) in order to validate the proposed control schemes.
