All the circuits that we have analyzed are linear circuits and we must be more specific in defining a linear circuit. We can consider the most important consequence of linearity, the principle of ...

In this tutorial, we will show that by writing the Fourier series expansion of a periodic signal in an intuitively obvious form, it is possible to interpret Parseval’s equality energetically. In this ...

Abstract: In the distributed generation system, the grid impedance will seriously affect the stability of the grid-connected inverter, and the accurate measurement method of grid impedance is the key ...
