Title: SYSTEM AND METHOD FOR PROCESSING POWER
Abstract:
A power processing system has power controllers connected in series to form a string voltage. Each power controller has at least one switch mode power conversion stage and receives a synchronization signal, extracts power switching frequency from the signal, and generates a pulsating output voltage based on the extracted power switching frequency. At least one power controller receives electric energy from a power source, such as PV panel, groups of PV panels or substrings that each has multiple photovoltaic cells within them or any other power source known in the art. A method of processing power by synchronizing power controllers by receiving at least one synchronization signal in the power controllers, and generating a pulsating output voltage at each of the power controllers of the plurality of power controllers by receiving electric energy from at least one power source, converting the electric energy to the pulsating output voltage, extracting power switching frequency from at least one of the at least one synchronization signal, and generating the pulsating output voltage based on the extracted power switching frequency.
