How an electric vehicle will be charged forms a key part of the design process, dependent on whether you are developing a mild hybrid, plug-in hybrid or battery electric vehicle (EV). WIth many plug-in EVs adopting AC charging infrastructure, designs must include an on-board charger that converts mains power to a DC voltage.

On-board chargers require careful selection of passive components to ensure efficiency and reliability. In the latest Engineers' Insight, we look at the key requirements and design challenges of these systems.
