  2. Current limiting - Wikipedia

    en.wikipedia.org/wiki/Current_limiting

    An inrush current limiter is a device or devices combination used to limit inrush current. Passive resistive components such as resistors (with power dissipation drawback), or negative temperature coefficient (NTC) thermistors are simple options while the positive one (PTC) is used to limit max current afterward as the circuit has been operating (with cool-down time drawback on both).

  3. Inrush current limiter - Wikipedia

    en.wikipedia.org/wiki/Inrush_current_limiter

    When the circuit is closed, the thermistor's resistance limits the initial current. After some time, current flow heats the thermistor, and its resistance changes to a lower value, allowing current to flow uninterrupted. It is inherently impossible for 100% of supply voltage to appear on the protected circuit, as the thermistor must continue ...

  4. Fault current limiter - Wikipedia

    en.wikipedia.org/wiki/Fault_current_limiter

    A simple solution is to add electrical impedance to the circuit. This limits the rate at which current can increase, which limits the level the fault current can rise to before the breaker is opened. However, this also limits the ability of the circuit to satisfy rapidly changing demand, so the addition or removal of large loads causes unstable ...

  5. Constant-current diode - Wikipedia

    en.wikipedia.org/wiki/Constant-current_diode

    It is known as a current-limiting diode (CLD) or current-regulating diode (CRD). Internal structure. It consists of an n-channel JFET with the gate shorted to the source, which functions like a two-terminal current limiter (analogous to a voltage-limiting Zener diode). It allows a current through it to rise to a certain value, but not higher.

  6. Electrical ballast - Wikipedia

    en.wikipedia.org/wiki/Electrical_ballast

    An electrical ballast is a device placed in series with a load to limit the amount of current in an electrical circuit. A familiar and widely used example is the inductive ballast used in fluorescent lamps to limit the current through the tube, which would otherwise rise to a destructive level due to the negative differential resistance of the ...

  7. Current limiting reactor - Wikipedia

    en.wikipedia.org/wiki/Current_limiting_reactor

    Current limiting reactor. The main motive of using current limiting reactors is to reduce short-circuit currents so that circuit breakers with lower short circuit breaking capacity can be used. They can also be used to protect other system components from high current levels and to limit the inrush current when starting a large motor. [5]

  9. Tesla coil - Wikipedia

    en.wikipedia.org/wiki/Tesla_coil

    A current-limiting circuit is usually used to limit maximum primary tank current (which must be switched by the IGBTs) to a safe level. Performance of a DRSSTC can be comparable to a medium-power spark-gap Tesla coil, and efficiency (as measured by spark length versus input power) can be significantly greater than a spark-gap Tesla coil ...
