Featured Projects

Conformal Wearable Battery – Hybrid Electrical Energy Storage Systems

Developed a high energy supercapacitor-based power system for military applications, under collaboration. Integrated all of the components from an elaborate test bench into a portable and flexible-form prototype which has demonstrated a high performance and reliability. Developed an advanced control algorithm that allows a buck converter to work as a bi-directional buck-boost converter that keeps the system running continuously without interruption during state transition.

Pre-heating for Li-ion Battery Pack

Investigated a scheduled pre-heating technique for Li-ion battery by creating a system model on MATLAB for heat transfer and electrical energy balance processes. Created a pre-heating algorithm for lithium battery pack working in cold environment, allowing balancing both cell temperature and SOC without requiring precise characterization for the batteries.

Optimization for Power Loss Protection in Solid State Drives

Implemented high-speed design for a customized storage device consists of an FPGA controller managing 512GB storage of NAND flash ICs. Ensuring signal integrity for impedance matching and propagation delay throughout the device. Developed a dynamic voltage-scaling power backup system to extend the lifespan of capacitors in SSDs.

Holographic Processing Unit

Implemented the Extended Kalman filter (EKF) on various embedded platforms to process data from a 9-DOF Inertial Measurement Unit combining with Parallel Tracking and Mapping (PTAM) for motion estimation in AR applications.
