Job Role & Responsibilities

Role: Power Electronics Engineer

Technical/Functional:

• Motor Control Unit:

• Design high-voltage (>96V) motor controllers for BLDC, PMSM, and induction motors used in electric powertrains.
• Develop inverter power stages, including 2-level, 3-level, and multilevel topologies with MOSFETs, IGBTs, SiC/GaN devices.
• Optimize gate driver circuits, dead-time control, and protection mechanisms for reliable and efficient switching.
• Implement DC-link capacitor selection, busbar design, and snubber circuits to enhance system performance.
• Ensure compliance with ISO 26262 (Functional Safety), EMI/EMC standards, and automotive-grade reliability requirements.

• DC-DC Converter:

• Design and optimize isolated and non-isolated DC-DC converters (buck, boost, flyback, forward, LLC resonant, etc.) for EV auxiliary power supplies and high- voltage power distribution.
• Select and implement high-efficiency power semiconductor devices (MOSFETs, GaN, SiC), magnetics, and control ICs.
• Perform stability analysis, transient response testing, and loop compensation design for closed-loop converters.
• Ensure high power density, efficiency optimization, and EMI/EMC mitigation.

• Design multi-layer PCBs for power electronics applications, ensuring optimized trace routing, creepage/clearance compliance, and thermal dissipation.
• Work closely with PCB layout engineers to integrate power and control circuits, ensuring minimal parasitics and optimal switching performance.
• Collaborate with mechanical engineers for enclosure design, thermal simulation, and system integration.
• Conduct worst-case circuit analysis (WCCA), Design Failure Mode and Effects Analysis (DFMEA), and Hardware Safety Analysis.
• Develop hardware prototypes and conduct rigorous performance testing, thermal analysis, and efficiency characterization.
• Utilize oscilloscopes, spectrum analyzers, thermal cameras, and high-voltage test equipment for debugging and validation.
• Perform power stage simulations using LTSpice, PLECS, PSIM, MATLAB/Simulink, or Ansys Maxwell.
• Conduct EMI/EMC compliance testing, functional safety assessments, and HALT/HASS testing.
