Abstract: In this article, a time-domain test on the negative group delay behavior of a double-Li-structure microstrip circuit is proposed. The feasibility of the test is validated experimentally ...

Be careful with single-phase motors, as most single-phase motors have components to help them start or continue to run ...

Abstract: Circuit-breakers for electricity meter play a vital role in the normal operation of the terminal circuit and equipment of user. Therefore, it is of great practical significance to analyze ...
