POWER CONVERTER DEVICE

In order to protect a power converter arrangement (20) for two motors (M1, M2) from damage, comprising semiconductor arrangements (H1, H2), it is proposed that a total current (IS) is continuously formed from a first current (I1 actual) and a second current (I2 actual) by means of a control unit (21) and is compared with a predeterminable maximum value (Max), the control unit (21) has a memory means (SM), in which a priority level (PR) can be input by the user (1), said priority level (PR) describing the priority of one of the two machines (M1, M2), and the control unit (21) is further designed to reduce the current (I1 actual, I2 actual) of the respective machine (M1, M2) that does not have priority according to the priority level (P) when a maximum value (Max) is exceeded. 为了在用于两个马达(M1，M2)的具有半导体装置(H1，H2)的功率转换器装置(20)中保护该功率转换器装置免受损坏，建议：借助于控制单元(21)--从第一电流(I1实际)和第二电流(I2实际)中连续地形成总电流(IS)并将总电流(IS)与可预设的最大值(Max)进行比较，其中，控制单元(21)具有存储机构(SM)，在该存储机构中能够由用户(1)输入优先权等级(PR)，其中，优先权等级(PR)描述两个机器(M1，M2)之一的优先权，控制单元(21)还设计用于：在超过最大值
