High-Voltage Inverter Development

As a member of the Electrical and Powertrain Track at GUC Innovators, I contributed to the design, simulation, and implementation of a three-phase inverter for the team’s Brushless DC (BLDC) motors, powering our student-built electric racing vehicle.

The project involved:
-𝗖𝗶𝗿𝗰𝘂𝗶𝘁 𝗗𝗲𝘀𝗶𝗴𝗻 & 𝗦𝗶𝗺𝘂𝗹𝗮𝘁𝗶𝗼𝗻: Developed a three-phase full-bridge inverter using N-channel MOSFETs, isolated gate drivers, and protection circuits. Simulated switching behavior, current ripple, and phase voltages using LTspice.
-𝐏𝐂𝐁 𝐃𝐞𝐬𝐢𝐠𝐧 & 𝐋𝐚𝐲𝐨𝐮𝐭: Created compact, low-inductance PCB layouts with KiCad, separating high-power and low-power domains to minimize EMI and ensure high-voltage safety.
-𝐌𝐨𝐭𝐨𝐫 𝐌𝐨𝐝𝐞𝐥𝐢𝐧𝐠 & 𝐂𝐨𝐧𝐭𝐫𝐨𝐥: Built a MATLAB Simulink model of the BLDC motor to validate six-step commutation and PWM-based speed and torque regulation.
-𝐄𝐦𝐛𝐞𝐝𝐝𝐞𝐝 𝐅𝐢𝐫𝐦𝐰𝐚𝐫𝐞 𝐃𝐞𝐯𝐞𝐥𝐨𝐩𝐦𝐞𝐧𝐭: Programmed STM32 microcontrollers to generate complementary PWM signals with dead-time insertion and phase commutation logic, incorporating current sensing and serial debugging.
