TI's Integrated Transformer Module Technology Helps Further Increase Hybrid and Electric Vehicle Drive Times

     Texas Instruments (TI) has introduced a smaller, more accurate 1.5W isolated DC/DC bias power module UCC14240-Q1. Using proprietary integrated transformer technology, the UCC14240-Q1 helps designers reduce the size of power solutions in half for use in high-voltage environments such as electric vehicles, hybrid vehicles, motor drive systems, and grid-tied inverters.

     As the EV market booms, automotive design engineers are continually striving to improve efficiency and reliability, and reduce the weight of EV powertrains, which account for the largest overall vehicle mass. To achieve a smaller, more reliable system for extended driving range, engineers switched to a distributed power architecture, in which the isolated gate drivers are paired with a dedicated bias supply, thus increasing the system response to a single point. failure responsiveness. For example, if one of the bias supplies fails, the other bias supplies and their accompanying gate drivers can still function normally, helping to keep the car safe on the road.
