Automotive Cold Cranking Design Considerations

Focus:

A two-switch buck boost topology maintains a well regulated, battery-powered dc supply across wide voltage range even that experienced during cold cranking of engine. This approach offers certain design advantages and disadvantages versus a conventional SEPIC converter.

What you’ll learn:

• How to build a buck-boost, dc-dc converter for automotive applications
• How to maintain regulation of automotive dc power supplies in automotive applications
• How to improve efficiency, dynamic performance, and EMI of buck-boost converters
