For modern navy electric ship, the application of multiple shunt active power filters (SAPF) has become an attractive choice to mitigate the current distortion of the nonlinear loads. Multiple SAPF has the advantage of high power capacity and high reliability. Based on the introduction of SAPF, this paper analyzes the importance of paralleling SAPF in(More)
When the current reference of a shunt active power filter (SAPF) changes quicker than the output current can change, the output of the APF cannot precisely track the current reference. Undesired harmonics will be generated by the APF due to the controller saturation. Based on detailed analysis of the reason and consequences of the controller saturation(More)
Iterative modeling and simulation form an integral part of modern control system design. While industry engineers rely heavily on proprietary "legacy" models to rapidly develop and implement new control systems, others must initiate models to develop production-capable control systems. The design process has now been considerably improved by the(More)
In any distributed power system where the impedance of the generator is non-negligible compared to the impedance of its nonlinear loads, the source voltage typically contains some distortion. Specifically, US Navy ship power generators experience a significant amount of voltage distortion. Since shunt active power filters (SAPFs) normally use the waveform(More)
The horse series has long been a showcase of evolution. But in reality, this series is the best argument that can be presented against evolution from the fossil record.1 Creationists have various opinions on whether the horse series is in fact made up of different created kinds. This article addresses some of the current problems, and concludes that the(More)
Silicon-carbide junction field-effect transistors (JFETs) are maturing in performance, reliability, and manufacturability, especially with voltage ratings ranging from 600-1800 V. The vertical channel JFET (VJFET) with extremely low specific on-resistance (&lt; 0.25 Omega-mm<sup>2</sup>) is now available. In this paper, new results are reported on a(More)
