ALTERNATE CURRENT – DIRECT CURRENT CONVERSION
In most of the applications of power electronics, the input power is in the form of a sinusoidal wave coming from the mains network which is then converted to direct current.
In many cases the conversion is of the non-controlled type, with the use of diode rectifiers.
However, in some applications, such as, for example, some types of drives of ac and dc motors, it is necessary that the dc output voltage be controllable.
In this case, thyristor converters for the mains frequency phase control are used.
They are utilized in particular in high voltage dc power transmission or in all those applications where it is necessary to control the power flow in both directions between the dc side and the ac side.
This trainer has a modular structure and it consists of didactic panels installed on a vertical frame. It is supplied with a theoretical and practical manual.
