Lead Power Electronics Engineer
THE PURPOSE:
The Power Electronics division is responsible for conceptualizing, designing, building, and testing the electrical power components in the Hyperloop system. These components include variable frequency drives for propulsion and levitation, energy storage systems, charging systems, wiring and cable assemblies, and the associated control hardware and control algorithms. We are seeking a Sr Power Electronics Engineer at our Los Angeles facility to join our diverse, experienced team in designing power electronics and battery systems for one of the most challenging transportation applications on Earth.
THE ROLE:
The Lead Power Electronics Engineer will take the ownership of the design, build, integration, test, and validation of the power stage at assembly level for all power converters/inverters. Key components in the power stage include SiC power module, HV busbar assembly, HV bulk caps, gate drives, and HV input/output filters.
Specifically, this position is responsible for:
- Identifying the requirements at functional level of all related power converters/inverters
- Conducting benchmarking studies on existing state of arts at both component level and assembly level in various technology areas
- Providing system/assembly topology and design concepts
- Conducting performance analysis, including steady state and transient behaviors
- Evaluating safe margins on system stability, ripple voltage and current, transient voltage overshoot, and thermal
- Identify system/assembly level fault conditions, analyze failure modes, provide fault management strategies, and implement fault protection mechanism
- Own all power stage components - including sourcing, build, inventory, and failure logging
- Identifying system/assembly level test requirements and provide test plan documents
- Writing test setup design documents, overseeing and commissioning the test setup fixtures
- Conducting & overseeing all tests at system/assembly level
- Leading trouble shooting and failure analysis efforts with temporary fix & long term solutions
- Providing test report documents
- Providing improvement design (optimal design) based on test results
