How does a Two Way Switch Work - Wiring Connection and Demonstration One of the simple yet interesting connection diagrams that young engineers learn in their lab is the staircase lighting setup. Perhaps most of us might have already used it without paying much attention to how it works. Staircase lighting at home or at any other place, for that matter, is normally done with something called a two-way switch. … |

Thyristor Commutation Techniques To turn on a Thyristor, there are various triggering methods in which a trigger pulse is applied at its Gate terminal. Similarly, there are various techniques to turn off a Thyristor; these techniques are called Thyristor Commutation Techniques. It can be done by bringing the Thyristor back into the forward blocking state from the forward conduction state. To bring the… |

Short-Circuit Protection Circuit Short circuit protection is an unintended connection between two terminals which are supplying power to the load. It can happen both in an AC and a DC circuit. If it is an AC supply, then a short circuit can trip the power supply of the whole area, but there are fuses and overload protection circuits at many levels, from the power station to the house. And if it is a DC… |
