Abstract :
This paper presents the project and the implementation of a high frequency isolation pre-regulator for applications in UPS systems using an easy implementation control technique, which uses fewer sensors and has good performance (>90%), named self-control. The technique was carried out using a DSPIC from MICROCHIP. A 1 kW prototype was assembled and its experimental waveforms will be presented on this paper.
