Deputy Manager-Firmware

Job description

**Job Description** - Firmware Development for Inverter/Drive Control - Develop and release stable, 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.
