Job Description: Power Electronics Firmware Senior Specialist

Position: Senior Specialist Power Electronics Firmware

Experience: 10–12 Years

Location: (Specify)

Department: R&D / Product Engineering

Employment Type: Full-time

Role Overview

The Senior Specialist – Power Electronics Firmware will lead the design, development, and optimization of embedded control firmware for advanced power electronic converters and UPS systems. This role requires deep expertise in closed-loop control algorithms, real-time embedded development, multilevel & interleaved PWM techniques, and load-sharing/paralleling control strategies. The candidate will work closely with hardware, system engineering, and validation teams to deliver high-performance, reliable, and certified power products.

Key Responsibilities

• Firmware Development & Control Algorithms
  • Design and implement real-time embedded control firmware for power converters (DC-DC, AC-DC, DC-AC, 3-level NPC, interleaved converters, UPS inverters).
  • Develop advanced closed-loop control algorithms:
    • PI/PR controllers
    • dq-frame control
    • current/voltage loop control
    • grid-tie and standalone inverter control
    • droop control
    • nonlinear/observer-based controls (as needed)
  • Implement digital PWM, dead-time control, PLL, current balancing, and modulation schemes (SPWM, SVPWM, 3-level modulation, interleaved PWM).
  • Develop and optimize firmware for DSP/MCU platforms (TI C2000 preferred).
• Paralleling & Load Sharing
  • Lead the development of paralleling algorithms for multi-converter and UPS systems (N+1 redundant, hot-sync, load-share control).
  • Implement communication-based and droop-based load-sharing control loops.
  • Ensure system stability during synchronization, phase alignment, current sharing, and transient events.
  • Troubleshoot dynamic instability, oscillations, harmonics, and cross-current issues in paralleled systems.
• Architecture, Design & Documentation
  • Define firmware architecture, state machines, safety routines, and diagnostic strategies.
  • Develop detailed design documentation, test plans, and release notes.
  • Ensure compliance with quality processes (MISRA-C, IEC/UL, documentation standards).
• System Integration & Validation
  • Work closely with hardware teams to optimize sensor interfaces, protection circuits, and control bandwidth.
  • Conduct lab testing of converters/UPS systems, tuning control loops, and managing EMI/thermal/efficiency trade-offs.
  • Perform root-cause analysis and debug failures at system, firmware, and hardware levels.
• Leadership & Collaboration
  • Mentor junior engineers in embedded development and control theory.
  • Work cross-functionally with hardware, mechanical, compliance, and product teams.
  • Drive innovation in converter topologies, control techniques, and software processes.

Required Skills & Expertise

Technical Expertise

• Strong hands-on experience (10–12 years) in embedded firmware for power electronics.
• Deep understanding of closed-loop control of converters/inverters (dc-link control, current/voltage loops, PLL, PR, droop, dq-control).
• Expertise in paralleling of converters/UPS including sync control, load sharing, circulating current minimization.
• Strong experience with TI C2000 family (F280x, F2837x, F28004x, F2838x or similar).
