Job Description
Firmware Development for Inverter/Drive Control - Develop and release reliable, productive, 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 recent control strategies, efficiency improvements, and algorithm enhancements.
Develop self-diagnostic features to reduce service costs and improve system reliability.
