As an element of power electronics, converters are an integral part of any electrical drive train. The fundamental task of the converters is to ensure that currents and voltages of converters (or rectifiers or inverters) are regulated and all components in the overall system are supplied with the ideal current or voltage ratings.

However, inverters can do much more than transform currents and voltages. While a great deal of attention is paid to the most expensive component in the drive system, energy storage, the converter's potential to significantly improve efficiency and efficiency is often underestimated.

This context is explained below.

The converter is a key component for an economical & efficient overall system

With a share of about two percent, the power electronics, i e the converter, represents a comparatively low cost share in the overall system. By far the largest share of the total costs is caused by the battery at a cost of about 50%. However, at first glance, saving the battery does not represent an attractive option to lower costs - the loss of range would be painful. However, precisely controllable converters open up their potential for efficiency and cost-effectiveness:
