摘要： A target pole-close timing determining unit corrects a breaker characteristic correction signal of a preceding turn-on phase by using a correction amount which is proportional to an absolute value of the interpolar voltage upon turn-on of the proceeding turn-on phase, and a correction amount which is proportional to an elapsed time after a target pole-close timing of the preceding turn-on phase, to generate a subsequent phase interpolar voltage signal, and determines a target pole-close timing of the subsequent turn-on phase at a timing when the subsequent phase interpolar voltage signal is equal to or smaller than a threshold value.

摘要： Provided is a system for soft switching of an electromechanical relay in a lighting control system using a sensor to detect a specified non-zero position in the electrical input waveform. Following this non-zero position, an adaptive time delay is applied before activation of the relay coil. An error detection circuit measures a time error between relay operation and the zero electrical input condition. This error signal is used to update the adaptive time delay for future relay operations. Using such a procedure has been shown to limit electrical stress on the relay, and therefore lengthen its life.

摘要： A system includes a relay, an actuation circuit, and an actuation delay circuit. The relay is coupled to a source of an input voltage or current waveform. The relay includes an actuation coil. The actuation circuit detects a peak or valley of a rectified voltage ripple waveform. The rectified voltage ripple waveform is generated from the input voltage or current waveform. The actuation circuit also causes an actuation voltage to be provided to the actuation coil. The actuation delay circuit delays the actuation circuit from providing the actuation voltage. The actuation delay circuit is configured based on the peak or valley of the rectified voltage ripple waveform. The actuation delay generated by the actuation delay circuit causes the relay to begin allowing current to flow to a load device at a time coincident with a zero-crossing time value of the input voltage or current waveform.

摘要： A control arrangement for a circuit breaker station includes a central control system and, for each of the circuit breakers, a circuit breaker operating unit connected to the central control system to obtain switching instructions and to the respective circuit breaker to control the operation thereof. The central control system and the circuit breaker operating units each have a local clock that are synchronized with one another. The central control system is, during use, arranged to calculate a point of time for switching each of the circuit breakers based on measured voltages, currents, and circuit breaker positions, and to send the point of time in a switching instruction to the circuit breaker operating unit. Each of the circuit breaker operating units is arranged to switch the circuit breaker, to which it is connected, at the point of time which is received in the switching instruction from the central control system.

摘要： A hybrid switch circuit includes a hybrid switch that couples an input conductor connected to an AC power supply to an output conductor connected to a load. The hybrid switch includes a power semiconductor in parallel with an electromagnetic relay. A control circuit turns on the hybrid switch by turning on the power semiconductor at a zero-voltage crossing of the AC voltage to provide a conductive path and then closing the relay to provide a conductive bypass path that bypasses the power semiconductor. The control circuit turns off the hybrid switch by opening the relay and subsequently turning off the power semiconductor at a zero crossing of the load current. The control circuit operates in response to a hybrid switch control signal that indicates whether an operating fault condition exists.
