摘要： The invention has for its subject-matter an impressed voltage inverter power circuit with a higher number of voltage levels than three (in general 2n+1). This circuit, of the NPC (Neutral Point Clamped) type, can provide a voltage at 2n steps in the zero to plus/minus V range across the "load", through a suitable arrangement of (n) elemental filters (RC) of a resistive capacitive divider and of two series of 2n semiconductor (D,S;D',S') circuits. Using clamp diodes (DC) and suitable openings and closings of the semiconductor (D,S) circuits acting as switches the voltage load on the semiconductors (D,D') can be brought below the safe operation values of the semiconductors and equal to one n-th of the voltage V, thereby to operate in a reliable range irrespective of the value of V.

摘要： An improved electric power conversion system comprising a multi-phase bridge circuit (3) is composed of semiconductors such as thyristors (TY1...TY6) and an associated firing circuit (31). It is so constructed that: if the AC input current Iac flowing in said bridge circuit (3) is equal to or larger in value than the DC output current Idc flowing out of the bridge circuit, it will be decided that an inner defect or fault is caused, and possible expansion of inner defect will be prevented by disabling the firing circuit (31) to extinguish said thyristors in the bridge circuit, and if the AC input current Iac is smaller than the DC output current Idc in value, the bridge (3) is permitted to continue the operation of power conversion, thus eliminating unnecessary interruption which otherwise would be caused by exterior disturbances. Also, an improved electric power conversion system may be equipped with a device to prevent an adverse effect from being caused by abnormal rise of thyristors' temperature.
