摘要： A static converter is disclosed. In at least one embodiment, the static converter includes a power converter circuit which has a plurality of interconnected module branches, wherein each module branch has one or more electrically series-connected two-pole submodules as switchable voltage sources which each include a capacitor as an energy store and power semiconductors as electronic switching elements. A device for precharging the capacitors is included, including at least one power electronics device for providing an adjustable precharge current. The at least one power electronics device, being supplied with power by an auxiliary supply system and being connected to a converter bridge via a precharge transformer, can be used to achieve a sufficiently high voltage level for the capacitors of the submodules when the converter is started up so as to achieve firstly the minimum voltage for supplying power to the power semiconductors and secondly the minimum voltage for synchronization to the systems. A method for starting up such a converter is also disclosed.
摘要翻译：公开了一种静态转换器。在至少一个实施例中，静态转换器包括具有多个互连的模块分支的功率转换器电路，其中每个模块分支具有一个或多个电串联连接的两极子模块作为可切换电压源，每个电压源包括作为能量储存和功率半导体作为电子开关元件。包括用于对电容器进行预充电的装置，包括用于提供可调节的预充电电流的至少一个电力电子装置。可以使用由辅助电源系统供电并通过预充电变压器连接到转换器桥的至少一个电力电子设备，以便在转换器启动时为子模块的电容器实现足够高的电压电平以便首先实现向功率半导体供电的最小电压，其次实现与系统同步的最小电压。还公开了一种启动这种转换器的方法。
