Power transfer units

Power transfer units integrated circuits and reference designs


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.

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.
