Power conversion system

摘要

This disclosure relates to a power conversion system to power a variable impedance load with a variable power source, the power conversion system comprising a power converter including input terminals adapted to receive variable power from the variable power source and output terminals providing a converted power to the variable impedance load based on the variable power received at the input terminals. The power converter increases the input voltage to an output voltage. The power converter is configured to reflect a source impedance of the variable power source to the variable impedance load.

1. A power conversion system comprising:
an input terminal adapted to receive variable power having an input voltage from a variable power source having a source impedance; an output terminal adapted to provide converted power having an output voltage to a variable impedance load, the variable impedance load receiving a load voltage based on the output voltage; a power converter including a switching controller, power switches controlled by the switching controller, a transformer coupled to the power switches, a rectification circuit configured to rectify an alternating current output from the transformer, and input and output capacitors, the switching controller configured to switch the power switches in an alternating manner at a duty-cycle that is independent of the input or output voltage or current, to increase the input voltage to the output voltage, the power converter configured to reflect the source impedance of the variable power source to the variable impedance load.
