Principal Power Architect:

Areas of Responsibilities:

Architect advanced high-voltage, high-power DC-DC converter topologies (e.g., LLC, PSFB, interleaved buck/boost, flyback) specifically tailored for use with SiC/GaN-based power modules in energy systems. Define scalable and modular power architectures that supply and interface with wide-bandgap-based converters for solar inverters, battery energy storage systems (BESS), grid-tied systems, and DC fast chargers. Lead design of isolated and non-isolated DC-DC supplies with wide input/output ranges (e.g., 100 V-1500 V), supporting fast transient loads and high switching speeds inherent to SiC/GaN technologies. Own development of analog and digital control systems, ensuring fast, stable response and integration with wide-bandgap switching dynamics. Direct the selection and specification of magnetics, isolation techniques, and thermal strategies suitable for high-frequency, high-efficiency power stages. Ensure full compliance with safety (UL, IEC), EMI/EMC (CISPR/IEC 61000), and grid-interconnect standards relevant to energy platforms. Collaborate across functions--including SiC/GaN switch designers, packaging engineers, and system architects--to co-optimize performance and reliability. Provide technical leadership, mentoring, and system-level oversight throughout architecture, design, validation, and productization. Drive IP generation, architecture documentation, and technology roadmaps aligned with the company's energy product strategy.

Technical Skills:

Expert in DC-DC converter topologies: Buck, Boost, Flyback, Forward, PSFB, LLC, Interleaved, Multi-phase. Expertise in wide-bandgap semiconductors (SiC/GaN) and digital power control. Proficiency in control loop design: voltage/current-mode control, Type II/III compensation, digital control. Strong knowledge of magnetics design: transformer and inductor design for high efficiency and low EMI. Proficient in high-voltage isolation techniques and safety-compliant designs (UL1577, IEC 62109). Deep understanding of EMI/EMC suppression, filter design, and compliance to IEC 61000, CISPR. Skilled in thermal modeling, derating, and power density optimization for harsh environments. Simulation tools: LTspice, SIMPLIS, PSIM, PLECS, MATLAB/Simulink. Familiarity with digital power controllers, firmware interaction, and telemetry features. Knowledge of grid interface standards, MPPT algorithms, and power module integration. * Knowledge of MPPT, multi-port converters, and BMS interfacing
