WebbCurrent Interruption devices or CIDs are devices that are built into any electrical circuit aimed to cut off the flow of current. CIDs are basically tasked with the prevention of incidents like short circuits and open circuit or electrical overload. Current interruption devices are also known as circuit breakers are very similar to switches ... WebbBy assuming the maximum phase of the tank current, we obtain a relation for the lock range. Besides, the effects of parasitic capacitors on the lock range have been probed. The analysis shows that the greater the phase difference between the tail current and injected signal, the phase of the tank current increases and, consequently, the lock range also …
