Power Electronics Internship Fall/Winter 2023

Power Electronics Engineer Internship Fall/Winter Break 2023

Power Electronics Engineers at Lunar are responsible for the full product development lifecycle of power electronics systems that recast day-to-day energy use in homes and on the go. As an intern, you will support these activities and will be expected to own/execute projects from beginning to end with mentorship.

Lunar Energy was founded to transition homes to 100% clean energy—making our electricity greener, our air cleaner and our energy more safe, secure and reliable for all. We’re a fast-growing, global company building the world’s best clean energy products to electrify all homes and connect communities to form clean, resilient virtual power plants.

On a given day at Lunar, you’ll likely…

• Work closely with Lunar Energy's Electrical Engineering team on exciting designs for energy storage application
• Detailed design of power electronic systems from 10W – 10kW, DC/DC converters, offline isolated power supplies, and inverters including the selection of topology, semiconductors, magnetics design, schematic design and layout, EMC and design of various safety aspects
• Bring up, and testing of systems to validate functionality, optimize performance, and evaluate critical characteristics
• Collaborate to create efficient test and validation mechanisms for the individual components as well as the complete system and support of the development of custom test cards
• Work across functions such as mechanical, thermal, reliability, and firmware engineering to optimize the product

Desired Skills:

• Students in M.S or Ph.D. program with focus on power electronics
• Detailed understanding of active and passive component losses in power conversion and the various means to reduce/mitigate those losses
• Familiarity with various topologies (two-level, multilevel, soft switching, etc.) and ability to analyze, select, and design topologies best suited for a given application
• Knowledge of sensor design to measure converter parameters in real time, in a noisy environment 
• Familiarity with magnetics design and specification, applications of various core materials for both power and filtering, knowledge of winding structure and optimization, and insulation strategies
• EMC design and optimization. Understanding of EMC theory applied to both PCB layout as well as filter designs
• Ability to design schematics and conduct layout design or review as it applies to power conversion
• Strong lab skills with working knowledge of the tools and techniques for power conversion test and analysis (e.g., use of oscilloscopes, impedance analyzers, sources, and loads in an environment with both high voltages and currents, and high common-mode and differential-mode noise)
