Power Electronics Engineer

Responsibilities

• Design and develop advanced power electronics systems, including:
• AC-DC converters (Flyback, Forward, LLC, PFC)
• Isolated and non-isolated DC-DC converters (Buck, Boost, Buck-Boost, SEPIC)
• Battery Management Systems (BMS) for Li-ion / LiFePO4
• Motor control systems (BLDC / PMSM – FOC preferred)
• EV chargers, inverters, and industrial power supplies
• Perform:
• Power stage design and magnetics calculations
• Transformer and inductor design
• Efficiency optimization and thermal calculations
• Select, evaluate, and validate:
• MOSFETs, IGBTs, SiC/GaN devices
• Gate drivers, current sensors, shunt amplifiers
• Protection components (TVS, MOV, snubbers)
• Design and validate:
• Overcurrent, overvoltage, short-circuit, reverse polarity protection
• EMI/EMC mitigation (filter design, grounding, layout best practices)
• Thermal management (heatsinks, airflow, thermal simulation)
• Perform:
• Oscilloscope-based switching waveform analysis
• Efficiency, ripple, transient response, and load testing
• Integrate power stages with:
• Embedded control firmware (PWM, ADC sampling, control loops)
• Closed-loop control algorithms (PID, FOC, current/voltage regulation)
• Support:
• Design validation testing (DVT)
• Pre-compliance testing (EMI/EMC)
• Transition from prototype to production
