Abstract

Styrmetod för ett aktivt filter kopplat till ett elektriskt system. Styrmetoden innefattar: mätning av en spänning vid de† elektriska systemet för att härleda en ström, jämförelse av den härledda strömmen med en referensström, härledning av en strömfelsvektor från jämförelsen, uppsättning av ett tröskelvärde för strömfelet, skapande av ett första strömflöde mellan en likströmskälla och det elektriska systemet basera† på strömfelsvektorn med användning av ett första switchmönster, när strömfelet är under tröskelvärdet, och skapande av att andra, annorlunda, strömflöde mellan likströmskällan och det elektriska systemet basera† på strömfelsvektorn med användning av ett andra switchmönster, när den härledda strömmen är över tröskelvärdet.
