Full-GaN Multi-Output Embedded TV Power Supply

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:

Hands-on experience with circuit design.

Familiarity with Plecs /FEA simulation software.

Completed coursework in Power Electronics.
