600 V DC Voltage Regulator Circuit Module
The main technical function of the proposed voltage regulator is voltage stabilization. It is capable of stabilizing an input voltage ranging from 0 to 600 Vdc to an output voltage ranging from 100 to 560 Vdc, with a maximum current of 800 mAdc and maximum power dissipation of 100 W. The unit also exhibits good […]
SCR Voltage Regulator Circuit
In this article I have explained how to build a highly efficient voltage regulator circuit using an SCR and some other external components. This SCR voltage regulator circuit being a switching kind of regulator is more efficient than the normal 3 pin voltage regulators, or the transistor zener based series pass regulators circuits. How the […]
3 Terminal Fixed Voltage Regulators – Working and Application Circuits
The popular 3 terminal fixed regulators available today are in the form of IC 7805, IC 7809, IC 7812, IC 7815, and IC 7824, which correspond to fixed voltage outputs of 5 V, 9 V, 12 V, 15V, and 24 V. These are called fixed voltage regulators since these ICs are able to produce excellent […]
