Abstract: A wind turbine is provided. The wind turbine includes a mechanical system, an electrical system and a controller. The controller is for determining an electrical capability limit of the electrical system according at least in part to one or more operating conditions of the wind turbine and one or more environment conditions of a site of the wind turbine, comparing the electrical capability limit of the electrical system and a mechanical capability limit of the mechanical system, and controlling the electrical system to operate at the smaller one of the electrical capability limit and the mechanical capability limit. A method for controlling a wind turbine comprising a mechanical system and an electrical system is also provided.

Abstract: The present disclosure relates to a method for controlling voltage balance of a serialized power switching device, comprising generating a reference voltage based on actual individual voltage of each switch of the serialized power switching device or setting a reference voltage based on supplied voltage to the serialized power switching device; determining an individual blocking voltage mismatch of at least one switch when existing a difference between the reference voltage and the actual individual voltage of at least one switch, wherein the individual voltage mismatch is based on the difference between the reference voltage and the actual individual voltage; calculating an individual delay mismatch for the at least one switch; and compensating the individual delay mismatch for the at least one switch. The present disclosure also relates to a system for controlling voltage balance of a serialized power switching device. The present disclosure also relates to a power switching device.

Abstract: A method used to control the operation of a converting device such that it can provide multi-level output voltage for loads. This method comprises at least the steps of: determine whether the load which the converter is providing electricity for is operating under the first condition or the second condition; generate the first pulse signal after determining that this load is operating under the first condition, select at least one of at least three different current paths, such that when the converter is selecting any of the current paths, it can provide output voltage at the same level; as well as generate the second pulse signal after determining that this load is operating under the second condition, such that the converter can perform the regular energy conversion operations.

Abstract translation: 一种用于控制转换装置的操作使得其可以为负载提供多级输出电压的方法。 该方法至少包括以下步骤：确定转换器正在提供电力的负载是否在第一条件或第二条件下运行; 在确定该负载在第一条件下运行之后产生第一脉冲信号，选择至少三个不同电流路径中的至少一个，使得当转换器选择任何电流路径时，它可以提供相同的输出电压 水平; 以及在确定该负载在第二条件下操作之后产生第二脉冲信号，使得转换器可以执行常规能量转换操作。

Abstract: The present disclosure relates to an integrated power semiconductor packaging apparatus and a power converter containing the integrated power semiconductor packaging apparatus. The integrated power semiconductor packaging apparatus comprises a plurality of power semiconductor devices and an electrically insulative substrate formed integrally. The electrically insulative substrate comprises a flat surface, at least one separation wall protruding from the flat surface and a flow channel inside the electrically insulative substrate. The at least one separation wall is configured to separate the flat surface into a plurality of flat areas, and each of the plurality of flat areas is configured to receive one of the plurality of power semiconductor devices. The flow channel is configured for allowing a coolant flowing through to remove heat from the plurality of power semiconductor devices.
