Job Description

Full-GaN Multi-Output Embedded TV Power Supply

Your role

Key responsibilities in your new role

Key Motivation (Why Wide-Bandgap / GaN)

Wide-bandgap (WBG) devices such as GaN offer:

• Low gate charge (Qg)
• Low output capacitance (Coss)
• Zero reverse-recovery

These characteristics indicate:

• High switching-frequency capability
• Enablement of new/alternative power converter topologies beyond conventional approaches

Topology Choice

The project adopts a new Asymmetrical Half-Bridge (AHB) fly back topology

This is selected instead of an LLC resonant topology

Target application: multi-output embedded TV power supply

GaN is used in both stages:

• PFC stage (Power Factor Correction)
• Half-bridge stage (AHB flyback)

Study Scope / Work Items

Hardware evaluate multi-output regulation performance

• Focus: regulation behavior/interaction across multiple outputs using the AHB full-GaN solution

System loss calculation and efficiency estimation

• Performed via PLECS simulation and measurement
• Includes analysis of overall converter losses under the proposed architecture

Your profile

Qualifications and skills to help you succeed

• Target Majors: Undergraduate/Graduate students in Electrical and Computer Engineering (ECE),
• Preferable Qualifications:

1. Hands-on experience with circuit design.
2. Familiarity with Plecs /FEA simulation software.
3. Completed coursework in Power Electronics.
