Cycloconverter

The main electrical energy forms commonly available are in constant DC (direct current) and constant AC (alternating current). Yet for various applications, the several forms of these two energies are used. For this conversion purpose, several converters like inverters, rectifiers, choppers and cycloconverters are employed. The cycloconverters can in fact transfer AC power of a … Read more

Dual Converter

Dual converter, the name itself says two converters. It is really an electronic converter or circuit which comprises of two converters. One will perform as rectifier and the other will perform as inverter. Therefore, we can say that double processes will occur at a moment. Here, two full converters are arranged in anti-parallel pattern and … Read more
