Problems solved by technology

Due to the constraints of the circuit principle, although the input voltage range of the secondary or cascaded buck circuit is larger than that of the traditional circuit, the improvement space is still not ideal
The improvement of the algorithm also means the increase of the complexity of the algorithm, which is not easy to promote in practical applications.

Abstract

The invention provides a dual buck converter of a pre-posed buck current-doubling circuit. The converter comprises a buck current-rising circuit and a dual-buck circuit. A first output terminal of the buck current-rising circuit is connected to a first input terminal of the dual-buck circuit; a second output terminal of the buck current-rising circuit is connected to a second input terminal of the dual-buck circuit; and thus the buck and current rising processing is carried out on an input voltage in advance by using the buck current-rising circuit and then the processed voltage is transmitted to the input terminal of the dual-buck circuit. According to the invention, the structure is simple; the operation is convenient; and the buck effect is obvious. Moreover, the circuit structure is easy to extend; A plurality of units are connected in parallel in front of the dual-buck circuit and thus the buck processing is carried out on the input voltage, wherein each unit is formed by one electrolytic capacitor and three power diodes.

Description

technical field [0001] The invention relates to the technical field of power electronic conversion, in particular to a double-buck converter with a pre-step-down current doubler circuit. Background technique [0002] A DC-DC power converter is a power conversion device that can convert DC voltage. It converts an unadjustable DC voltage into an adjustable DC voltage. The buck converter realizes the step-down operation of the input voltage. The ratio of the output voltage to the input voltage of a traditional buck circuit is the duty cycle of the switch. When it is necessary to reduce a large voltage to a small one, the traditional buck circuit has a very small duty cycle and cannot be used in practical applications. [0003] With the continuous expansion of new energy applications, new energy development technologies require buck converters to have a wide input voltage range. One method is to introduce a transformer module, such as a forward converter, to reduce the duty cy...
