Voltage controller

<p>A voltage controller, also called an AC voltage controller or AC regulator is an electronic module based on either <a href="/facts/Thyristors/DYPV2ftl">thyristors</a>, <a href="/facts/TRIAC/HRvWQkja">triodes for alternating current</a>, <a href="/facts/Silicon-controlled_rectifier/ep3HLxmS">silicon-controlled rectifiers</a> or <a href="/facts/Insulated-gate_bipolar_transistor/XRafcaFE">insulated-gate bipolar transistors</a>,  which converts a fixed voltage, fixed frequency <a href="/facts/Alternating_current/qxICS3xa">alternating current</a> (AC) electrical input supply to obtain variable <a href="/facts/Voltage/EN2po6N2">voltage</a> in output delivered to a resistive <a href="/facts/Electrical_load/IX0XBAqB">load</a>. This varied voltage output is used for dimming <a href="/facts/Street_light/Uuw2oH1y">street lights</a>, varying heating temperatures in homes or industry, speed control of <a href="/facts/Industrial_fan/CVXfejAD">fans</a> and <a href="/facts/Winding_machine/89dWHGSs">winding machines</a> and many other applications, in a similar fashion to an <a href="/facts/Autotransformer/uUFUTD0N">autotransformer</a>. Voltage controller modules come under the purview of power electronics. Because they are low-maintenance and very efficient, voltage controllers have largely replaced such modules as <a href="/facts/Magnetic_amplifier/EgURfWqs">magnetic amplifiers</a> and <a href="/facts/Saturable_reactor/Qmw8LTkj">saturable reactors</a> in industrial use.
