Good understanding of power electronics components and modules, including power semiconductors, gate drivers, magnetic components (transformers, inductors), passive components, connectors, device characterization, converter topologies (DC-DC, DC-AC, AC-DC), mechanical packaging, thermal management, modulation techniques, and control methods. Clearly define test plans and procedures, perform test cases and generate test reports for board/module bring-up, design verification and system integration, and support other tests including end-of-line, environmental / electrical stress and safety-of-flight.
