In this article, we will explore AC analysis with the “.AC” directive, one of the main techniques for evaluating the frequency response of circuits. It is one of the most powerful features of SPICE ...

The circuit in Figure 1 provides a low-cost, isolated ac-line monitor that measures ac-line-voltage level and has some other unique capabilities. The analysis of the circuit is straightforward: When ...

Abstract: Research on synchronous instability caused by AC short-circuit faults in wind farms connected to flexible DC transmission systems primarily focuses on fault-phase synchronization mechanisms ...

Abstract: This paper proposes a novel method for calculating winding inductances in electrical machines using mesh-based magnetic equivalent circuit (MEC). In the proposed framework, the inductances ...
