Abstract
Frequency converters for converting electrical energy, in particular for a vehicle electrical system, are proposed which have individual partial frequency converters and include at least one half bridge, as a result of which there are at least one high-side switch and one low-side switch with a predeterminable number of switches. The high-side switch and low-side switch have a common connection that is connected to means that produce the electrical energy. Parallel to the half bridge, there is an intermediary circuit capacitor whose capacitance should be as low as possible. To this end, the switches of the half bridge are triggered offset from one another so that the current to be supplied by the intermediary circuit capacitor remains as low as possible. Various possibilities are disclosed for the arrangement of the chokes of the frequency converter.
