Popis: For testing purposes or even for to reduce the transient regime when connect the equipment to the power network it is conveyable to detect zero-crossing voltage. The designed circuit use conventional electronic components to perform a zero crossing detection and give appropriate output signal to be used. Using this device has possibilities to analyze the effects of connecting in different moments of time of switching elements. This can be a part of complex test equipment to have adjusting possibilities of zero-crossing point offset. Importance of using zero-crossing device is about the transient regime, most often causes power network instability or a process of degradation of switching apparatus. Even if the detection of voltage crossing is easy to achieve with a small number of components, to achieve an adjustment of the time difference shifted from zero-crossing point required the design of a complex schematics. This circuit provides pulses at the same time towards the zero-crossing of voltage.
