Singapore beBeePower Full time $96,000 - $144,000
High Voltage Power Converter Design Specialist

This role involves working on cutting-edge power converter design projects, leveraging expertise in high-voltage applications and advanced converter architectures.

The ideal candidate will have a strong background in designing and testing multi-level converters or cascaded H-bridge systems, with a focus on optimizing performance, efficiency, and reliability.

Key responsibilities include:

  • Designing isolated and non-isolated power conversion stages (DC-DC, AC-DC, DC-AC) including dual-active bridges, phase-shifted full-bridge, LLC, multi-level, and cascaded H-bridge topologies for high-voltage applications.
  • Developing and optimizing multi-level converter topologies for MV AC interfaces with modular and scalable design strategies.
  • Architecting and analyzing cascaded H-bridge inverters for grid interfacing, power flow control, and harmonic optimization.
  • Implementing and validating high-performance Silicon Carbide (SiC) power semiconductor-based switching stages for improved efficiency, power density, and thermal handling.

Requirements:

  • Strong foundational knowledge in power converter architectures (hard- and soft-switched), especially for SST applications.
  • In-depth understanding of SiC device behavior, high-frequency switching design, and thermal/electrical integration challenges.
  • Expertise in multi-level and cascaded topologies, modulation techniques, and isolation coordination.
  • Proficiency in simulation tools (PSIM, LTSpice, PLECS, MATLAB) and schematic/PCB design software (Altium, KiCad, OrCAD).
  • Skilled in test bench development and debugging of high-power prototypes, including fault testing and waveform analysis.
