Multi-phase inverter bridge for use in e.g. permanent magnet synchronous motor utilized in technical system, has output short circuit formed between phases of bridge and producing deceleration of rotary current generator

摘要

The bridge (20) has a combination of self-conducting power transistors (21-23) and self-closing power transistors (24-26), which are interconnected with each other such that the self-conducting power transistors are optionally connected with fly-wheeling diodes. An output short circuit formed between phases (31-33) of the bridge produces deceleration of a rotary current generator (10). The self-conducting power transistors and the self-closing power transistors are connected in series with each other. Independent claims are also included for the following: (1) a technical system (2) a method for stopping an axis.
