Job Description

Job Description: Technical Lead – Central Inverter Development

Location: India -Bangalore

Experience: 12–15 years

Domain: Power Electronics – Solar / BESS / Grid-tied Systems

Role Summary

Lead the design, development, and industrialization of high-power central inverters (250 kW – multi-MW range) for solar PV and energy storage applications. Own system architecture, drive cross-functional execution, and ensure compliance with grid codes and reliability targets.

Key Responsibilities

1. System Architecture & Design

- Define end-to-end architecture for central inverter systems:
- Topology selection (NPC, ANPC, T-Type, Modular Multilevel)
- Power stage design (IGBT / SiC based)

- Define:

- DC bus structure (1000V / 1500V systems)
- Thermal management strategy (air / liquid cooling)
- Efficiency optimization (>98.5%)

2. 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)

3. 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

4. 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)

5. Thermal & Mechanical Integration

- Work with mechanical teams for:
- Heat sink design
- CFD validation
- IP rating (IP54/IP65 outdoor systems)

6. Reliability & Safety

- Define:
- Derating strategies
- Lifetime calculations (mission profile-based)

- Conduct:

- FMEA / DFMEA
- HALT / HASS testing

- Ensure functional safety alignment (where applicable)

7. Team Leadership

- Lead a cross-functional team:
- Power electronics
- Controls
- Mechanical
- Validation

- Mentor engineers and drive design reviews

8. Vendor & Cost Optimization

- Work with vendors for:
- Magnetics, semiconductors, capacitors

- Drive:

- Cost reduction (?/kW)
- Design-to-cost initiatives

Required Qualifications

Education

- B.E./BTech in Electrical / Power Electronics
- MTech / PhD preferred

Experience

- 10+ years in power electronics design
- Strong experience in:
- Central / string inverters OR
High-power converters (
- 100 kW)
