Title: POWER CONVERSION SYSTEM AND METHOD
Abstract:
A power conversion system is to be used with an energy source. A plurality of conversion units are used in series via their output with the energy source output. A positive pin of a first converter and the negative pin of a last converter of the series are for connection to an output (14, 16) of the energy source, and for each two neighboring converters in this series a negative pin of an upstream converter is connected to a positive pin of a downstream converter which both pins are decoupled from the energy source except for the positive pin of the first converter and the negative pin of the last converter. A master monitor unit is adapted to monitor the output power of the energy source and to control the input voltage of each conversion unit synchronously in dependence on the monitored output power. In this way, a set of conversion units are configured, with the conversion units sharing the output from the energy source. This provides a scalable system.
