Part # Distributor Manufacturer Product Category Description
LR-4010 Automationdirect.com Not Provided Line/Load Reactors Line reactors used on the input side of a drive protect the AC drive from transient overvoltage conditions typically caused by utility capacitor switching. Input line reactors also reduce the harmonics associated with AC drives, and are recommende...

  • Mitigation Methods for Parasitic Turn-on Effect Due to Miller Capacitor - White Paper
    One of the common problems faced when switching an IGBT is parasitic turn-on due to Miller capacitor. This effect is noticeable in single supply gate driver (0 to +15V). Due to this gate-collector coupling, a high dV/ dt transient created during IGBT turn-off can induce parasitic turn-on (Gate

  • Shunt Regulator Operation (.pdf)
    the system and charges the capacitor in the power supply. above its normal energy level. The shunt regulator operates by sensing the voltage level. of the supply, and in the event the voltage level rises above a pre-set threshold, the shunt. regulator switches on a resistor to ground that dissipates
  • 2Pro Protects Low-Power Systems Application Note (.pdf)
    Lightning, inductive load switching, or capacitor bank switching may cause transient overvoltage conditions in AC line voltage applications such as white goods and appliances. Metal Oxide Varistors (MOVs) are typically used for transient overvoltage suppression in AC line voltage applications
