An EV Auxiliary Power Module with Wide Input and Output Voltage Range Using GaN and Planar Magnetics
Application
The final deliverable of this project is a DCDC converter used for electric vehicles (EVs), with the input range of 180V~940V and the output voltage of 6V~16V. The rated power is 4.1kW. It is desired to use wide-bandgap devices to reach high efficiency (>95%) and high-power density (>5kW/L), such as 1200V GaN with two level design, or 650V GaN with a three-level topology.
Research
Previous two-stage dcdc design
The main research area of this project involves finding the best topology and control, and designing the planar magnetics so that we can shrink the size and weight. The project is sponsored by Hella Electronics Corporate.
How WBG Can Help
The project immediately uses GaN or SiC devices. It also explores the impact of WBG devices on magnetics design.
