  • Systems and methods for synchronizing converter modules
    Patent number: 10439513
    Abstract: Various examples are directed to a converter system comprising first and second series-connected converter modules and a synchronization circuit. The synchronization circuit may modulate a reference signal onto a carrier signal to generate a synchronization current signal and the synchronization current signal to an output current of the converter system to generate an aggregated output current. A first converter module may receive the aggregated output current from a first current sensor and generate a first reproduced synchronization signal at least in part from the aggregated output current. A first switch control signal for switching at least one switch at the first converter may be generated based at least in part on the first reproduced synchronization signal.
