Abstract
A power converter circuit includes an input and an output. A supply circuit is configured to receive an input signal from the input and to generate a number of supply signals from the input signal. A number of converter units are provided. Each of the plurality of converter units is configured to receive one of the plurality of supply signals and to output an output signal to the output.
Claims29
A power converter circuit, comprising:
- an input and an output;
- a supply circuit configured to receive an input signal from the input and to generate a plurality of supply signals from the input signal;
- and
- a plurality of converter units, wherein each of the plurality of converter units comprises a converter unit output port conductively connected to the output of the power converter circuit, and each of the plurality of converter units is configured to receive one of the plurality of supply signals and to output an output signal via the converter unit output port to the output of the power converter circuit, wherein
- the supply circuit comprises a plurality of supply units connected in series, wherein each of the plurality of supply units is configured to output one of the supply signals,
- each of the plurality of supply units is associated with one of the plurality of converter units,
- the plurality of converter units comprises n converter units, wherein n is an integer greater than or equal to two,
- at least n−1 of the n converter units comprises a coupling switching element configured to couple the supply unit associated with the one of the plurality of converter units to a reference potential node, wherein the reference potential node is conductively connected to the output of the power converter circuit, and
- each of the plurality of supply units comprises a first capacitive storage element, and a first switching element connected in series with the first capacitive storage element.
