For this purpose, the determination of a trigger-release time reserve is related to a corresponding evaluation. In such a manner, it is possible, for example to dynamically determine whether a desired process can be carried out in the total length thereof or automatically disjointed, thereby making it possible to generate corresponding warning signals.

摘要： The aim of the invention is to provide an inexpensive electronic arc quenching system which reliably detects and processes a non-functional state of opening of the bypass contacts (1) of a circuit device for starting a motor for example due to malfunction or mechanical stress. For this purpose, the voltage across a parallel circuit device consisting of the bypass system (1) and a semiconductor device (2) is detected and the circuit elements (1, 3, 4) are controlled in accordance therewith. If the bypass system (1) is unintentionally opened, an arc voltage is applied to the bypass contacts. When this voltage is detected, the control unit (8) switches on the semiconductor device (2) so that the current flows across the semiconductor device (2) and the arc is extinguished.

摘要： The aim of the invention is to provide a method with which the load current and thus the load moment of an asynchronous motor that is controlled via a phase-controlled two-phase thyristor power controller can be easily influenced so as to allow a smooth starting operation. According to a first embodiment of the invention, the ignition point (tIgn+1) is determined in the controlled phase (L1 and L2) in order to adapt the flow angles of the subsequent current half waves. According to a second embodiment, the ignition point (tIgn) of the subsequent current half waves is brought forward in both controlled phases (L1 and L2) .

摘要： This invention concerns a three-phase current regulator with interrupt-performed phase control characterized by a simple, cost-effective design, particularly by the use of a simple microcontroller (1) with only one or two interrupt inputs. This is made possible by forming zero crossover signals (U0A, U0B, U0C) the edges of which can be used for interrupt control. Interrupt routines in the program of the microcontroller (1) control the times for output of firing signals (ZA, ZB, ZC) starting exclusively from the zero crossovers as data about the three-phase network.
