In many applications, phase shift modulation (PSM) has been proven to be a promising supplement of pulse frequency modulation (PFM) in LLC resonant converter. However, steady-state analysis of PSM LLC converter is not thoroughly studied yet. This paper presents a generalized PSM LLC model which can provide accurate prediction on resonant voltage and current behavior, dc gain and all the other steady-state...
The pollution of harmonics in power system becomes serious because of power electronic devices used widely. As an important device to eliminate the pollution, Active power filter (APF) becomes more popular. The result of ip iq harmonics current detection method based on instantaneous reactive power theory is the sum of all harmonics current. But sometimes it is not necessary. In response to the problem,...
