2.6 CONVERTER SIZE SELECTION

Within the specified voltage field, the CS300 converter supplies the same rated direct current independently of the voltage itself. The increase of the output voltage causes an increasing in the transferred power, whereas inverters are devices with a typically constant transferred power (the supplied current decreases with the increasing of the output voltage).

As for the choice, therefore, the calculation is based on a common unit, the direct current of the intermediate circuit, which, as for the inverters, is not mentioned into the product instruction manual and has therefore to be calculated. Furthermore, the confrontation between the two foreseen functioning classes has to be homogeneous (IEC 146 class 1 and 2).
