  2. Schottky diode - Wikipedia

    en.wikipedia.org/wiki/Schottky_diode

    The Schottky diode's low forward voltage drop is good for energy-efficient applications, because little energy is wasted to heat. This makes them useful as blocking diodes in stand-alone ("off-grid") photovoltaic (PV) systems which prevent batteries from discharging through the solar panels at night.

  3. Transient-voltage-suppression diode - Wikipedia

    en.wikipedia.org/wiki/Transient-voltage...

    A transient-voltage-suppression diode can respond to over-voltages faster than other common over-voltage protection components such as varistors or gas discharge tubes. The actual clamping occurs in roughly one picosecond , but in a practical circuit the inductance of the wires leading to the device imposes a higher limit.

  5. Flyback diode - Wikipedia

    en.wikipedia.org/wiki/Flyback_diode

    Diagram of a simple circuit with an inductance L and a flyback diode D.The resistor R represents the resistance of the inductor's windings. A flyback diode is any diode connected across an inductor used to eliminate flyback, which is the sudden voltage spike seen across an inductive load when its supply current is suddenly reduced or interrupted.

  6. Blocking oscillator - Wikipedia

    en.wikipedia.org/wiki/Blocking_oscillator

    Basis of solid-state Blocking oscillator The waveform generated by this circuit This Joule thief circuit, a blocking oscillator, can be used in order to power a light-emitting diode from a 1.5V battery for a relatively long period of time, with the brightness being a tradeoff.

  7. Boost converter - Wikipedia

    en.wikipedia.org/wiki/Boost_converter

    An unregulated boost converter is used as the voltage increase mechanism in the circuit known as the "Joule thief", based on blocking oscillator concepts. This circuit topology is used with low power battery applications, and is aimed at the ability of a boost converter to "steal" the remaining energy in a battery.

    Surge protection device (SPD) for installation in a low-voltage distribution system. A surge protector, spike suppressor, surge suppressor, surge diverter, [1] surge protection device (SPD), transient voltage suppressor (TVS) or transient voltage surge suppressor (TVSS) is an appliance or device intended to protect electrical devices in alternating current (AC) circuits from voltage spikes ...
