Job Role & Responsibilities
Role: Power Electronics Engineer
Technical/Functional:
Motor Control Unit:
Design 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.
