Job Description
The Power Electronics Intern will support the design, development, and testing of high-voltage, high-power DC-DC converters for energy storage systems utilizing recycled batteries, focusing on optimizing efficiency, thermal performance, and cost-effectiveness.
Key Responsibilities
- Design and develop high-voltage, high-power DC-DC resonant converters for recycled battery integration
- Optimize converters for soft-switching to ensure high efficiency across various battery voltages
- Develop transformer models and perform trade-off analyses on power density, thermal constraints, and cost
- Prototype and validate power stages through bench testing to verify thermal performance and efficiency
Requirements
- MS or PhD candidate in Electrical Engineering with a focus on Power Electronics
- Deep theoretical and practical understanding of Resonant DC-DC converter modulation schemes e.g., frequency modulation, phase-shift control
- Expertise in magnetics design using Ansys Maxwell for transformer modeling, including inductance matrix extraction and detailed winding core loss analysis
- Proficiency in simulation tools such as Simulink and LTspice for transient and steady-state circuit analysis
- Hands-on experience with Altium Designer for multi-layer PCB layout, specifically for high-power and high-voltage creepage clearance requirements
- Ability to design and develop high-voltage, high-power 1500V, 50kW DC-DC resonant converters for recycled battery integration
- Ability to optimize converters to achieve consistent soft-switching, ensuring high efficiency across a wide range of battery voltages during both charge and discharge modes
- Ability to develop high-fidelity transformer models and conduct detailed trade-off analyses between power density, thermal constraints, and cost
- Experience in prototyping and validating power stages, performing bench testing to verify thermal performance and efficiency targets
