• Develop and implement control strategies for Grid-Following (GFL) and Grid-Forming (GFM) converters.
• Define hierarchical control architecture including current control, voltage control, DC-link control, PLL/synchronization, power control and grid-support functions.
• Design firmware architecture for active/reactive power control, voltage/frequency control, droop control, virtual impedance, black start and islanding operation, as applicable.
• Develop control functions for BESS PCS including charge/discharge control, SOC-based power limitation, grid support and operating-mode management.
• Develop PV inverter control functions including MPPT, DC-link control, active/reactive power control and grid-code compliance.
• Define state machines, operating modes, protection coordination, fault handling and system-level sequencing.
• Translate grid-code and customer requirements into software/system requirements and control specifications.
• Design interfaces between DSP/MCU control firmware, FPGA, gate drivers, sensing, protection and supervisory controllers.
• Lead implementation of real-time control algorithms on DSP/MCU/SoC platforms.
• Perform simulation and control validation using MATLAB/Simulink, PLECS, PSCAD, or equivalent tools.
• Develop and execute MIL/SIL/HIL validation strategies for converter control systems.
• Support grid-code testing, certification, FAT/SAT and field commissioning.
• Analyze field issues and drive root-cause analysis, corrective actions and firmware improvements.
• Establish reusable control software architecture and common platforms across PV inverter and BESS PCS products.
• Mentor firmware engineers and provide technical leadership for control-system development.
