PhD in Electrical Engineering and Computer Science
My internship at Delta Electronics’ Milan Power Electronics Laboratory in Durham, NC has been an amazing experience. I am working on developing firmware for a 22kW bidirectional EV charger prototype, focusing on improving digital filtering and control strategies using a Texas Instruments DSP. Implementing an exponential moving average filter and a finite state machine improved the system’s flexibility, efficiency, and reliability. I also introduced soft-start control to reduce inrush current and burst mode for better efficiency at light loads. Besides coding, I applied object-oriented programming concepts to make the firmware more modular and easier to maintain. The working culture here balances productivity with work-life balance, encouraging teamwork, open communication, and flexibility. The lab is well equipped, and I’ve learned a lot from skilled technicians about practical prototype design. I’m very grateful to Dr. Feng Jin, Dr. Peter Barbosa, and the whole MPEL team for their support during this valuable internship.
