Application Engineer Intern: traction inverter debug and embedded systems
Supported Global Key Account Customers on microcontroller projects across automotive and industrial applications, acting as the bridge between ST silicon and customer products.
- 01Debugged a custom traction motor inverter with Lauterbach JTAG and StellarStudio
- 02Resolved PWM timing faults, gate-driver issues, and current-sensing calibration errors
- 03Independently diagnosed DC bus instability and implemented a parallel-capacitor fix
- 04Built an STM32 proximity-sensing system end to end, sensor to speaker
- 05Authored PWM and space-vector modulation parameterization guides
I supported Global Key Account Customers in microcontroller project development across automotive and industrial applications. The core of the internship was hands-on debug of a customer's custom traction motor inverter: working through PWM timing faults, gate-driver issues, and current-sensing calibration errors with Lauterbach JTAG hardware and the StellarStudio IDE, and identifying firmware bugs in the motor control algorithms with corrected code.
- Diagnosed independently that the DC bus required stabilization; proposed and implemented a parallel-capacitor fix between the inverter and the power supply.
- Built an STM32-based proximity sensing system end to end: ADC signal processing, timed interrupt logic, PWM/DAC audio output, analog low-pass filter, amplifier stage, speaker.
- Authored parameterization guides covering PWM and space-vector modulation theory for internal and customer-facing use.
- Conducted hardware teardowns of competitive automotive electronics modules and delivered pivot-table analyses and presentations to ST marketing.
Motor-inverter debug is ESC debug. The math doesn't care which side of gravity it's on.
