Welcome!
Hi! I am a third-year EE Ph.D. student at EECS, UC Berkeley, advised by Prof. Robert Pilawa-Podgurski in the Pilawa Research Group. I received my B.Eng. in Electrical Engineering from Huazhong University of Science and Technology. Before starting my Ph.D., I spent one year as a master’s student at Stanford University.
My research focuses on high-performance power delivery for AI infrastructure. I am particularly interested in fast-transient point-of-load voltage regulation, coupled magnetics, hybrid switched-capacitor converters, high-density integration, and power management integrated circuits (PMICs). My broader goal is to co-design converter architectures, magnetics, control, and power integration for next-generation data centers.
Research Highlights
Fast-Transient Control of Trans-Inductor Voltage Regulators
IEEE APEC 2026
A single compensation-winding current sensor replaces per-phase high-bandwidth sensing in constant-on-time TLVR control. A six-phase TLVR hardware prototype demonstrates 240-A operation and fast load-transient response with simpler sensing and routing for processor power delivery.
Single-current-sensor series-capacitor buck converter with ZB-TLVR
IEEE APEC 2026
A series-capacitor buck architecture with coupled magnetics reduces DC flux bias and improves transient response. The work develops single-current-sensor control and phase-shift modulation for current balancing, with a compact 24-V-to-1-V, 120-A hardware prototype.
High-performance design methodologies for data center power delivery
IEEE APEC 2024
Scalable hybrid switched-capacitor topologies for data-center power delivery, with zero-voltage-switching intermediate rails and reusable buck-stage components. The paper develops the operating principles and validates the design using a 12-V-to-1-V, 80-A, 1-MHz prototype.
