Job Description

Research Fellow / Engineer (Power Electronics) - CSY1

Posting Start Date: 07/10/2025

Schemes of Service: Research

Division: Professional Officers

Employment Type: Fixed Term

As a University of Applied Learning, SIT works closely with industry in our research pursuits. Our research staff will have the opportunity to be equipped with applied research skill sets that are relevant to industry demands while working on research projects in SIT.

We are seeking a talented Power Electronics Engineer or Research Fellow to design and optimize high-frequency magnetic components and resonant power conversion circuits for advanced aerospace power supply applications. In this role, you will collaborate closely with project supervisors and team members to achieve technical objectives, resolve design challenges, and ensure projects are completed on schedule. The ideal candidate will possess strong expertise in both magnetic design and resonant topology optimization, enabling the delivery of high-efficiency, compact, and reliable solutions. Candidates with relevant R&D work experience will be considered. The project supervisor will provide on-the-job training on simulation tools.

Key Responsibilities

  • Design and develop custom high-frequency transformers (planar, ferrite-core, and PCB-embedded) for switching power converters. Model parasitics (leakage inductance, interwinding capacitance) for accurate simulation and EMI prediction. Analyze core and copper losses and apply thermal management strategies for high power density application. Build and evaluate transformer prototypes.
    Design resonant circuit topologies for high-efficiency DC-DC conversion. Calculate resonant tank parameters to achieve ZVS/ZCS and optimize switching performance. Model and simulate resonant circuits under varying load and voltage conditions using circuit simulation software. Develop advanced control strategies to meet the application requirement.

Job Requirements

  • Master/Ph.D. degree in Electrical/Electronic Engineering (Power Electronics focus preferred).
  • Proficiency in magnetic design tools (e.g., Simplis Magnetics Design Module, ANSYS Maxwell, etc) and circuit simulation platforms (Simplis, PLECS, PSIM, LTspice, etc) is preferred.
  • 3+ years' experience in designing high-frequency magnetic components and resonant converters, with relevant academic research as a valued addition.
  • Familiarity with GaN/SiC device circuit design application and high-frequency switching considerations.
  • Understanding of safety (IEC/UL) and EMC/EMI compliance requirements.
