Bourns Push-Pull Transformers

Push-pull DC-DC converters are becoming more common in electric vehicle applications where galvanic isolation is a requirement. They produce low EMI emissions, are highly efficient and occupy a small footprint, so they are extremely attractive for automotive applications. The push-pull configuration can be used to produce power for battery management systems (BMS), onboard chargers and traction inverters that isolate high-voltage circuits from low-voltage circuits.

This application note highlights how Bourns Model HCTSM8 series transformers isolate power in DC-DC converter systems, with details of the push-pull topology and how these transformers can also be used to supply the bias voltage for an isolated insulated gate bipolar transistor.
