Power transfer units

Block diagram


Our integrated circuits and reference designs for power transfer units (PTUs) help you design systems such as static transfer switches (STS), automatic switchgears, AC-power distribution units (PDUs) and automatic transfer switches (ATS) with increased reliability and accuracy.

Design requirements

Modern power transfer unit designs often require:

  • Accurate sensing of high voltages and high currents with or without isolation.
  • Improved fault monitoring and protection.
  • Protected SCR gate driver designs and electromechanical relay controls.
  • Efficient auxiliary power supply designs for control electronics and gate drivers.
