  2. Load dump - Wikipedia

    en.wikipedia.org/wiki/Load_dump

    Load dump. Load dump means the disconnection of a powered load. It can cause two problems: failure of supply to equipment or customers. large voltage spikes from the inductive generator (s) In automotive electronics, it refers to the disconnection of the vehicle battery from the alternator while the battery is being charged.

  3. Alternator (automotive) - Wikipedia

    en.wikipedia.org/wiki/Alternator_(automotive)

    Alternator (silver) mounted on a V8 engine. An alternator is a type of electric generator used in modern automobiles to charge the battery and to power the electrical system when its engine is running. Until the 1960s, automobiles used DC dynamo generators with commutators. As silicon-diode rectifiers became widely available and affordable, the ...

  4. Diode bridge - Wikipedia

    en.wikipedia.org/wiki/Diode_bridge

    A diode bridge is a bridge rectifier circuit of four diodes that is used in the process of converting alternating current (AC) from the input terminals to direct current (DC, i.e. fixed polarity) on the output terminals. Its function is to convert the negative voltage portions of the AC waveform to positive voltage, after which a low-pass ...

  5. Alternator - Wikipedia

    en.wikipedia.org/wiki/Alternator

    Alternator. Alternators made in 1909 by Ganz Works in the power generating hall of a Russian hydroelectric station (photograph by Prokudin-Gorsky, 1911). [1] An alternator is an electrical generator that converts mechanical energy to electrical energy in the form of alternating current. [2] For reasons of cost and simplicity, most alternators ...

  6. Voltage regulator - Wikipedia

    en.wikipedia.org/wiki/Voltage_regulator

    An integrated circuit voltage regulator. A voltage regulator is a system designed to automatically maintain a constant voltage. It may use a simple feed-forward design or may include negative feedback. It may use an electromechanical mechanism, or electronic components. Depending on the design, it may be used to regulate one or more AC or DC ...

  7. DIAC - Wikipedia

    en.wikipedia.org/wiki/Diac

    The DIAC ( diode for alternating current) is a diode that conducts electrical current only after its breakover voltage, V BO, has been reached momentarily. Three, four, and five layer structures may be used. [1] Behavior is similar to the voltage breakdown of a triac without a gate terminal. When breakdown occurs, internal positive feedback ...

  9. Voltage spike - Wikipedia

    en.wikipedia.org/wiki/Voltage_spike

    Voltage spikes, also known as surges, may be created by a rapid buildup or decay of a magnetic field, which may induce energy into the associated circuit. However voltage spikes can also have more mundane causes such as a fault in a transformer or higher-voltage (primary circuit) power wires falling onto lower-voltage (secondary circuit) power ...
