Because of their high efficiency and small footprint, push-pull DC-DC converters are becoming popular for galvanic isolation in electric vehicles, BMS and on-board chargers. These converters require a transformer to transfer power from primary to secondary in each switching cycle. Learn about a successful solution using Bourns HCTSM8 transformers and TI SN6501 drivers to isolate a 12 V bus rail in a communications system or power supply for switching IGBTs.
