H4PFC using HV BDS GaN and CCM/CRM PFC comparison - Shenzhen, 深圳, China
Originally posted 27 October 2026 by the employer.
About the role
This internship focuses on evaluating an H4PFC architecture implemented with bidirectional high-voltage GaN devices to address rectifier bridge thermal limitations and improve power supply efficiency. The project compares CRM versus CCM operation through simulation loss analysis and hardware evaluation using the ICE3PCS01 PFC controller.
What you'll do
- Build and set up CCM H4PFC evaluation hardware using the Infineon ICE3PCS01 PFC controller.
- Execute hardware evaluations measuring efficiency, thermal behavior of power stage components, stability, and operating waveforms.
- Run simulations comparing CRM and CCM operation to determine peak currents, RMS currents, and switching behaviors.
- Complete detailed CRM and CCM loss calculations covering conduction losses, switching losses, and loss contributors across operating tradeoffs.
- Summarize hardware and simulation findings to recommend preferred operating modes and power stage design adjustments.
What you'll need
- Current enrollment as an undergraduate or graduate student in Electrical and Computer Engineering (ECE).
- Completed coursework in Power Electronics.
Nice to have
- Hands-on experience with circuit design.
- Familiarity with Plecs or FEA simulation software.
Skills: PFC, GaN, CCM, CRM, Plecs, power electronics
