    摘要： The invention relates to a sub-module (10) for forming a multi-level converter (1) having a power accumulator (11), a power semiconductor circuit (12) which is arranged in parallel to the power accumulator (11) and has controllable power semiconductor valves (14, 15), a first connecting terminal (17) and a second connecting terminal (18), a power accumulator voltage drop at the level of the power accumulator (11) or a zero voltage at the level of the connecting terminals (17, 18) being producible depending on how the power semiconductor valves (14, 15) are controlled. The aim of the invention is to improve said sub-module such that as high a voltage as possible can be generated at its connecting terminals while at the same time increasing its reliability. Every power semiconductor valve (14, 15) comprises a series connection of power semiconductor units (19) that can be switched off and have the same direction of passage, every power semiconductor unit (19) being electrically conducting counter to the direction of passage.

    摘要： Converter with at least one phase module (2a, 2b, 2c), which has an AC voltage terminal (3/1, 3/2, 3/3) and at least one DC voltage terminal (p, n), wherein a phase module branch (6p1, 6p2, 6p3, Sn1, 6n2, 6n3) is formed between each DC voltage terminal and each AC voltage terminal, and wherein each phase module branch has a series circuit comprising submodules (7) which each have a capacitor (8) and at least one power semiconductor (T1, T2), with submodule sensors for detecting an energy stored in the capacitor (8) and with regulation means (9) for regulating the apparatus (1) as a function of the energy store energy values and predetermined desired values. In this case, unbalanced loading of the energy stores (8) of the said modules (7) is avoided. The regulation means (9) have a summation unit for summing the energy store energy values Uc whilst obtaining branch energy actual values (Uc sum p1,...Uc sum n3) and means for calculating the circuit current desired values as a function of the branch energy actual values, wherein the regulation means (9) are set up to compensate for imbalances in the branch energy actual values as a function of the circuit current desired values.

    摘要翻译： A转换器具有至少一个相位模块，AC电压端子和DC电压端子。 在每个直流电压端子和每个交流电压端子之间形成相模块分支。 每个相模块分支具有包含子模块的串联电路，每个子模块具有电容器，功率半导体和用于检测存储在电容器中的能量的子模块传感器，以及用于根据能量值和预定的期望值来调节装置的调节装置。 因此避免了能量存储单元的不平衡负载。 调节装置具有用于在获得分支能量实际值的同时求和能量值的求和单元和用于根据分支能量实际值计算电路当前期望值的装置。 调节装置根据电路电流期望值补偿分支能量实际值中的不平衡。

    摘要： The invention relates to a device (1) comprising: at least one phase module (2a, 2b, 2c) with an a.c. voltage connection (31,32,33) and at least one d.c. voltage connection (p,n), a phase module branch (6p1, 6p2, 6p3, 6n1, 6n2, 6n3) being arranged between each d.c. voltage connection (p,n) and the a.c. voltage connection (31,32,33) and each phase module branch (6p1, 6p2, 6p3, 6n1, 6n2, 6n3) having a series circuit of sub-modules (7), each of which has an energy accumulator (8) and at least one power semiconductor (T1,T2); and regulating means for regulating the device. The aim of the invention is to provide a device that can regulate circulating currents in a targeted manner. To achieve this, each phase module (2a, 2b, 2c) has at least one inductance (Lkr) and the regulating means are designed to regulate a circulating current that flows through the phase modules (2a, 2b, 2c).
