An important concept for safely switching power and protecting the load! Explanation of the definition of synchronous switching.
This document discusses the synchronization relationship between two AC power sources, A and B, in a switch that inputs these two systems. In switching between two AC power sources, the ideal switch is one where the waveforms before and after the switch appear almost unchanged from the load side. In high-speed power switching, synchronized switching is essential, and switching must occur at a timing where there is almost no phase difference between the two power sources. Furthermore, the synchronization relationship of the two power sources can be classified into two types: "sources that each have their own unique frequency" and "sources that are under synchronized control." For more detailed information, please refer to the related links below. [Overview] - In switching between two AC power sources, the ideal switch is one where the waveforms before and after the switch appear almost unchanged from the load side. - When there is a phase difference between the two power sources, inrush current may flow depending on the load equipment, so it is necessary to consider the impact on the load equipment. *For more details, please refer to the PDF document or feel free to contact us.

basic information
【Other Overview】 ■ If the switch uses an overlap switching method, the cross current between the two power sources during overlap may become excessive, posing a risk of switch damage or power system failure. ■ For switches that cause momentary interruptions due to the operation time of the switch, the phase difference between the two power sources is generally not a significant issue if the load equipment is good. ■ In high-speed power switching, synchronous switching is essential, and switching must occur at a timing where there is almost no phase difference between the two power sources. ■ The synchronization relationship of the two power sources can be classified into two types: "power sources with their own unique frequencies" and "power sources that are synchronized." ■ Synchronous switching is an important concept for performing power switching more safely and protecting the load. *For more details, please refer to the PDF document or feel free to contact us.
