FPGA-Based RISC-V Flight Control System

VHDL (Vivado) RTL Design

This project features the FPGA-based prototyping of a flight control system for rotary-wing UAVs. Built on a 32-bit RISC-V (CV32E40P) architecture, the system performs multi-sensor fusion by integrating I2C, SPI, and UART communication protocols alongside PWM and ADC interfaces. The implementation of the digital DShot protocol ensures high-precision motor speed management with ultra-low latency.

Industrial AC-DC Flyback Converter Series

Power Electronics PCB Design (Kicad)

This project series encompasses the design and development of three distinct Switched-Mode Power Supply (SMPS) boards, engineered in accordance with industrial standards during my internship. The designs include a 12W high-efficiency Flyback switcher based on the TNY288PG, a 4.2W power unit developed with the LNK605DG IC featuring constant current/voltage control, and a 10W industrial-grade dual-output power stage built on the VIPer22A architecture, specifically optimized for HVAC (air-conditioning) systems. Each design prioritizes critical engineering criteria, including AC-DC conversion efficiency, EMI/EMC compliance, thermal management, and compact PCB layout optimization.

LoRa Multiprotocol Mesh System

Schematic and PCB Design (Kicad) Antenna Tuning & RF Design (HFSS) Embedded C

Designed and implemented a multi-node LoRa Mesh network featuring 1 Master (LoRa+GSM) and 2 Slave nodes. Optimized the system to bridge remote areas without cellular coverage by routing local mesh data through a centralized GSM gateway for remote monitoring.

Conducted comparative RF antenna designs for the slave nodes, implementing both internal trace and external SMA antenna configurations. This allowed for performance benchmarking of signal integrity and range efficiency across different hardware form factors.

Design and Analysis of 868 MHz / 1.8 GHz CPWG Transmission Lines

RF Design & Analysis

Investigated the impact of critical length on 868 MHz and 1.8 GHz CPWG transmission lines, comparing theoretical literature values with optimized simulation results. Observed that critical length is governed not only by frequency but also significantly by physical layout constraints, demonstrating that standard closed-form equations often require empirical refinement via HFSS for high-precision system integration.
