Abstract
The present disclosure relates to an initial starting apparatus and method for a solid-state transformer, the initial starting apparatus comprising: a plurality of power conversion unit modules connected in series with each other; and a synchronization controller that provides a synchronization signal of a set cycle to the plurality of power conversion unit modules so that the plurality of power conversion unit modules operate according to the synchronization signal, wherein each of the plurality of power conversion unit modules may be started by determining a detected synchronization signal as a start signal when not in operation.
Claims8
An initial starting apparatus of a solid-state transformer, comprising:
- a plurality of power conversion unit modules connected in series with each other;
- and
- a synchronization controller configured to provide a synchronization signal of a set cycle to the plurality of power conversion unit modules such that the plurality of power conversion unit modules operate according to the synchronization signal, wherein each of the plurality of power conversion unit modules is started by determining a detected synchronization signal as a start signal when not in operation.
A method for initially starting a solid-state transformer that comprises a plurality of power conversion unit modules connected in series with each other, and a synchronization controller configured to provide a synchronization signal of a set cycle to the plurality of power conversion unit modules such that the plurality of power conversion unit modules operate according to the synchronization signal, the method comprising:
- determining whether a synchronization signal is input from the synchronous controller in each of the plurality of power conversion unit modules;
- checking whether the plurality of power conversion unit modules are currently operating if a synchronization signal is input, and determining as a synchronization signal if the plurality of power conversion unit modules are operating;
- and
- determining as a start command if the plurality of power conversion unit modules are not operating to start each of the power conversion unit modules.
