Abstract
A configuration circuit may be used with a power converter. The configuration circuit dynamically reconfigures one or more connections of output stages of a power converter to vary the output. A capacitive load may receive the output of the power converter.
Claims16
A power converter, comprising:
- an input circuit configured to receive an input voltage or current;
- an output circuit that is electrically isolated from the input circuit and is configured to generate a combined output voltage or a combined output current in response to the input circuit, wherein the output circuit includes a plurality of output stages, where each output stage of the plurality of output stages is configured to generate a respective partial output voltage or current, wherein the input circuit is configured to generate light energy in response to the input voltage or current, and wherein at least one output stage of the plurality of output stages includes one or more photosensitive cells configured to generate the respective partial output voltage or current in response to the light energy;
- a first output terminal and a second output terminal, wherein the first output terminal and the second output terminal are to be coupled to provide the combined output voltage or the combined output current to a load;
- and
- a configuration circuit coupled to the plurality of output stages to dynamically reconfigure a connection among the plurality of output stages.
