Job Description

Firmware Development for Inverter/Drive Control

- Develop and release secure, efficient, and optimized firmware for inverter-based compressor and fan motor drives.
- Implement motor control algorithms such as FOC, Sine PWM, Space Vector PWM (SVPWM), soft-start, protection logic, and dynamic load handling.
- Control Algorithm Implementation & Optimization
- Design, tune, and optimize control loops (current loop, speed loop, torque control, DC bus control).
- Improve efficiency, switching performance, and thermal behaviour through firmware optimization.
- Firmware Integration With System Controller
- Ensure seamless handshaking between inverter drive and main logic controller (communication protocols, signal mapping, error handling).
- Release interface specifications and communication test reports.
- Protection & Diagnostic Logic Development
- Implement inverter protection algorithms such as:
- Over-current, over-voltage, under-voltage
- Compressor stall, phase loss, rotor lock
- Over-temperature protection for power devices
- Develop diagnostic features, fault logging, and recovery procedures.
- Functional & Parametric Testing
- Prepare and execute firmware validation test cases on real hardware (compressor rigs, fan motors, inverter bench).
- Validate performance under different loads, temperatures, operating modes,



and power quality conditions.
- Support system-level EMI/EMC and safety testing.
- Tuning & Calibration
- Perform inverter tuning for different compressor and fan motor models.
- Generate tuning documents, calibration files, and release notes for production use.
- Validate tuning consistency across multiple units.
- Firmware Documentation & Release Management
- Prepare firmware specifications, architecture documents, and revision notes.
- Ensure proper version control, configuration management, and release procedures.
- Debugging & Issue Resolution

- Debug issues during prototype testing, field trials, and production.
- Perform root cause analysis for inverter performance issues, noise, heating, oscillation, and protection triggers.
- Release corrective firmware updates within defined timelines.
- Continuous Improvement & Innovation
- Introduce new control strategies, efficiency improvements, and algorithm enhancements.
- Develop self-diagnostic features to reduce service costs and improve system reliability.
