Abstract: A wind power converter device is provided. The wind power converter device includes grid side converters, generator side converters and a DC bus module. Each of the grid side converters includes grid side outputs electrically coupled to a grid and a first and a second DC inputs. Each two of the neighboring grid side converters are connected in series at the second and the first DC inputs. Each of the generator side converters includes generator side inputs electrically coupled to a generator device and a first and a second DC outputs. Each two of the neighboring generator side converters are coupled in series at the second and the first DC outputs. The DC bus module is electrically coupled between the grid side converters and the generator side converters.

Abstract: A wind power conversion system includes plural first converting circuits and a second converting circuit. The plural first converting circuits perform a power converting task, and include respective first generator-side terminals and respective first network-side terminals. The first generator-side terminals are electrically connected with a wind power generator. The first network-side terminals are electrically connected with corresponding secondary windings of an isolating transformer. The second converting circuit includes plural second generator-side terminals and a second network-side terminal. The second network-side terminal is electrically connected with the corresponding secondary winding of plural secondary windings of the isolating transformer. The second generator-side terminals are serially connected with the corresponding first generator-side terminals of the first converting circuits. When the second converting circuit is enabled, the power converting task of the plural first converting circuits is shared by the second converting circuit.
