Course Overview

DC-DC converters replace the traditional belt-driven alternator/generator in Hybrid and Electric vehicles. These converters are High Voltage power supplies that step down battery pack voltage to 13.5 – 14.00 to charge the vehicle battery and power vehicle systems. In this series, technicians will learn about the DC-DC Converter construction, operation, and using load testers, meters, and Scopes to test its operation.  Ford, GM, Honda, Lexus, Toyota and other popular products are featured in this course. 

At the conclusion of this series, technicians will learn how the DC-DC converter operates, different DC-DC designs from various manufacturers, failure modes, and how to test the system for output and electrical noise.
