Electrical & Electronic Design

Power electronics impacts our lives in so many ways - from new power circuits that extend battery life to voltage regulators that help manage and distribute energy more efficiently from the grid to the consumer. This fundamentals course covers several topics that a design engineer needs to understand when it comes to power management design.
