Development of FPGA controller based high step-up DC-DC converter using coupled inductor

Abstract

This paper proposes three phase high step up DC-DC converters are in need for applications, where increased loads are used. The proposed three phase DC-DC converter has with input-parallel, output series combination, accompanied by dual coupled inductors. The proposed converter inherits the advantage of being used in three phase applications, compared to the conventional converter. At the input, the presence of the paralleled dual coupled inductors shares the input current. The prototype circuit of the conventional converter has been modified by The prototype The proposed three phase converter has a rating of about 100 W output power at a switching frequency of about 40 kHz and satisfactory agreement between experimental and theoretical analysis has been observed. An output voltage of about 295 V has been harvested.
