The idea of home automation is not bounded to houses, the application area can be extended to security systems, auditoriums, function halls, Libraries etc. Home automation is just a catchy usage.Here, the medium for automation is not considered, only the switchboard connections are discussed. Every automation circuit finally has to control a relay through the […]
In power electronics chopper circuits, unidirectional power semiconductors are used. If these semiconductor devices are arranged appropriately, a chopper can work in any of the four quadrants. we can classify chopper circuits according to their working in any of these four quadrants  as type A, type B, type C, type D and type E. Let us
Choppers  A chopper is basically a dc to dc converter whose main function/usage is to create adjustable dc voltage from fixed dc voltage sources through the use of semiconductors. Types of choppers The main classification of the types of choppers is given in another post. Take a look – TYPES OF CHOPPER CIRCUITS There are
