1. High-Voltage Hardware Design
Lead the design and architecture of high-voltage power electronics hardware for e-motor drive systems (400V–800V+ EV platforms).
Design and optimize circuits such as:
Inverter power stage (IGBT/SiC MOSFET)
Gate driver circuitry
DC-link capacitor and busbar layout
Current/voltage sensing circuits
HV contactors, pre-charge, discharge path
EMI/EMC filtering, protection circuits (OCP, OVP, OTP)
Ensure compliance with derating guidelines for HV components (semiconductors, capacitors, inductors, connectors, insulation components).
Select semiconductor devices, gate drivers, PCB materials, HV connectors and insulation components.
Analyse power losses, switching behavior, thermal derating, and performance under automotive environments.
Support thermal design, cooling strategies, and packaging for power modules.
Perform circuit simulation and system modeling using tools such as:
SPICE, LTspice, PLECS, PSIM, Simulink.
Conduct worst-case analysis, derating analysis, fault modeling, and transient behavior studies.
Support FEA thermal/electrical analysis with CAE teams.
Lead prototype build, bring-up, and debugging of high-voltage hardware.
Define and execute DV/PV test plans for inverter and e-motor hardware.
Support testing in HV labs for switching performance, efficiency mapping, isolation testing, EMC, and environmental validation.
Analyze failures (root cause analysis) and implement corrective actions.
Ensure hardware meets relevant automotive standards:
ISO 26262 (functional safety)
ISO 21448 (SOTIF – where applicable)
LV123 / LV148 / ECE R100 for HV systems
EMC requirements per CISPR 25, ISO 7637, ISO 11452
Participate in FMEA/DFMEA, safety goals allocation, and hardware safety mechanism definition.
Work closely with cross-functional teams (E-Motor, Power Electronics, Mechanical, Thermal, Software, Control).
Guide junior engineers on HV hardware design.
Collaborate with suppliers and evaluate their technical proposals and component capabilities.
Provide design reviews, documentation, and technical reports.
RequirementsRequired
Bachelor’s or Master’s degree in Electrical Engineering, Power Electronics, Mechatronics, or related fields.
