The ferroresonant transformer, ferroresonant regulator or constant-voltage transformer is a type of saturating transformer used as a voltage regulator. These transformers use a tank circuit composed of a high-voltage resonant winding and a capacitor to produce a nearly constant average output voltage with a varying input current or varying load.
In the following example crowbar circuit, the LM431 adjustable zener regulator controls the gate of the TRIAC. The resistor divider of R 1 and R 2 provide the reference voltage for the LM431. The divider is set so that during normal operating conditions, the voltage across R 2 is slightly lower than V REF of the LM431. Since this voltage is ...
A Voltage controller thyristor based dimmer rack An electrical schematic for a typical SCR-based light dimmer. A voltage controller, also called an AC voltage controller or AC regulator is an electronic module based on either thyristors, triodes for alternating current, silicon-controlled rectifiers or insulated-gate bipolar transistors, which converts a fixed voltage, fixed frequency ...
An automotive wiring diagram, showing useful information such as crimp connection locations and wire colors. These details may not be so easily found on a more schematic drawing. A wiring diagram is a simplified conventional pictorial representation of an electrical circuit. It shows the components of the circuit as simplified shapes, and the ...

LM317 with heat sink. The LM317 is an adjustable positive linear voltage regulator.It was designed by Bob Dobkin in 1976 while he worked at National Semiconductor. [1]The LM337 is the negative complement to the LM317, which regulates voltages below a reference.
A bench power supply usually refers to a power supply capable of supplying a variety of output voltages useful for BE (bench testing) electronic circuits, possibly with continuous variation of the output voltage, or just some preset voltages. Some have multiple selectable ranges of current/voltage limits which tend to be anti-proportional. [2 ...
On single alternator circuits, the power may be split between the engine starting battery and the domestic or house battery (or batteries) by use of a split-charge diode (battery isolator) or a voltage-sensitive relay. Due to the high cost of large house battery banks, Marine alternators generally use external regulators.
