摘要：

This paper presents a high frequency isolated pre-regulator using the self-control technique, which aims to provide a 400Vdc link with input power factor correction. The main feature of self-control technique, as the OCC one, is the direct loop feedback from the input current, using the converter parameters for the current loop control. The input voltage sample is not necessary, as in several others PFC theories. The technique was carried out using a DSPIC from MICROCHIP. A 2kW prototype was assembled and its experimental waveforms will be presented on this paper.
