    en.wikipedia.org/wiki/Shunt_(electrical)

    Where devices are vulnerable to reverse polarity of a signal or power supply, a diode may be used to protect the circuit. If connected in series with the circuit it simply prevents reversed current, but if connected in parallel it can shunt the reversed supply, causing a fuse or other current limiting circuit to open.

  3. Zener diode - Wikipedia

    en.wikipedia.org/wiki/Zener_diode

    Reverse current is shown. Zener diodes are widely used as voltage references and as shunt regulators to regulate the voltage across small circuits. When connected in parallel with a variable voltage source so that it is reverse biased, a Zener diode conducts when the voltage reaches the diode's reverse breakdown voltage.

    J L, photogenerated current density (ampere/cm 2) J 0, reverse saturation current density (ampere/cm 2) r S, specific series resistance (Ω·cm 2) r SH, specific shunt resistance (Ω·cm 2). This formulation has several advantages.

    en.wikipedia.org/wiki/Commutator_(electric)

    This opposing field helps to reverse the lagging self-inducting current in the stator. So even for a rotor which is at rest and initially requires no compensation for spinning field distortions, the brushes should still be advanced beyond the perfect 90-degree angle as taught in so many beginners textbooks, to compensate for self-induction.

  6. Silicon controlled rectifier - Wikipedia

    en.wikipedia.org/wiki/Silicon_controlled_rectifier

    The device behaves as two diodes connected in series. A small leakage current flows. This is the reverse blocking mode. If the reverse voltage is increased, then at critical breakdown level, called the reverse breakdown voltage (V BR), an avalanche occurs at J1 and J3 and the reverse current increases rapidly. SCRs are available with reverse ...

    en.wikipedia.org/wiki/Brushed_DC_electric_motor

    In motor-generators, reverse current relays prevent the battery from discharging and motorizing the generator. Since D.C. motor field loss can cause a hazardous runaway or overspeed condition, loss of field relays [ 25 ] are connected in parallel with the motor's field to sense field current.

  8. Rectifier - Wikipedia

    Rather, a regulator increases or decreases current supplied to the load in order to maintain a constant output voltage. A simple passive shunt voltage regulator may consist of a series resistor to drop source voltage to the required level and a Zener diode shunt with reverse voltage equal to the set voltage. When input voltage rises, the diode ...

  9. Shunt generator - Wikipedia

    en.wikipedia.org/wiki/Shunt_generator

    Generator separately excited by battery Self exciting generators Series on left, shunt on right. A shunt generator is a type of electric generator in which field winding and armature winding are connected in parallel, and in which the armature supplies both the load current and the field current for the excitation (generator is therefore self excited).
