- Efficiency optimization (>98.5%)
- Power Electronics Development
- Lead design of:
- DC-AC inverter stage
- LCL filters and EMI/EMC compliance
- Gate driver and protection circuits
- Evaluate semiconductor technologies:
- IGBT vs SiC trade-offs (cost vs efficiency vs switching frequency)
- Control & Firmware
- Define and guide control algorithms:
- Grid synchronization (PLL)
- Current control loops (dq control)
- MPPT (if integrated)
- Grid support functionalities:
- Reactive power control
- LVRT / HVRT compliance
- Interface with DSP/FPGA teams
- Grid Compliance & Standards
- Ensure compliance with:
- IEC standards (IEC 62109, IEC 61727, IEC 61000)
- IEEE 1547
- Indian grid codes (CEA regulations)
- Lead certification efforts (CE, UL if export-focused)
- Thermal & Mechanical Integration
- Work with mechanical teams for:
- Heat sink design
- CFD validation
- IP rating (IP54/IP65 outdoor systems)
- Reliability & Safety
- Define:
- Derating strategies
- Lifetime calculations (mission profile-based)
- Conduct:
- FMEA / DFMEA
- HALT / HASS testing
- Ensure functional safety alignment (where applicable)
- Team Leadership
- Lead a cross-functional team:
- Power electronics
- Controls
