Description

In the “PowerDAC” project, a new approach for power amplifier systems is investigated. A topology, including a control/modulation scheme, has been synthesized by which a multilevel waveform can be created. This topology consists of a number of subsequent power stages, in which each stage has half the voltage and twice the switching frequency of the preceding stage. Compared to the conventional two-level approach, the power stage has been extended in such a way that the output filter can be reduced or even eliminated. A proof-of-concept prototype has been designed and realized, which will be used to demonstrate the capabilities.
