Abstract

The invention relates to a high step-up DC converter with switched inductors. The high step-up DC converter is technologically characterized by comprising an input DC voltage Vi, four inductors, five capacitors, 12 diodes and two MOSFET switching tubes which are connected together. The high step-up DC converter is reasonable in design, can realize high voltage gain, and meets the requirement for high gain in industrial application. The efficiency of the DC converter circuit is improved. The ripple of output DC voltage Vo is reduced. The cost performance of the DC converter circuit is improved. The high step-up DC converter can be widely used in the field of DC conversion.

Description

technical field [0001] The invention belongs to the technical field of direct current converters, in particular to a high boost direct current converter with switched inductance. Background technique [0002] In recent years, with the application of high-voltage DC switching power supplies, step-up DC / DC converters have become more and more popular in many industrial fields. According to the presence or absence of isolation, DC / DC converters can be divided into isolated and non-isolated converters. The isolated converter is to add the AC link to the basic DC-DC converter to achieve a higher voltage conversion rate. The AC link usually uses a transformer to isolate the input and output, so the converter is also called a direct-current converter. - AC-DC converter. Usually isolated DC converters are used in the following situations: (1) the output terminal and input terminal of the DC converter need to be isolated; (2) the ratio of the required output and input voltage is mu...
