Embodiment Construction

[0052] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of this application.

[0053] The invention provides a DC converter to solve the problem of high cost in the prior art.

[0054] Specifically, the DC converter, see figure 1 , including: N inverters 101, N first filters 102, intermediate frequency three-winding step-up transformer 103, two three-phase diode rectifier bridges 104 and two second filters 105; N is a positive integer greater than 1 ;in:

[0055] The DC sides of the N inverters 101 are connected in parallel, and the connection point is used as the i...

Abstract

The invention provides a DC converter. N inverters connected with a DC side in parallel are connected with an AC side through corresponding first filters in parallel to form N parallel branches separately. Loop impedance of corresponding inverters is increased through the first filters arranged in the N parallel branches, and circulating current among various parallel branches is reduced; and AC output of various parallel branches is imported into an intermediate frequency three-winding booster transformer for boosting transformation, so that the problem of high cost due to the fact that one booster transformer is arranged in each module in the prior art is solved, and application of the DC converter in a system with higher power and a higher voltage level is facilitated.

Description

technical field [0001] The invention relates to the technical field of direct current transmission, in particular to a direct current converter. Background technique [0002] With the continuous development and application of new energy, various forms of power generation capacity are becoming larger and larger. Due to the limitations of land resources and new energy resources, large-scale new energy sources are generally located in remote areas, and at this time large-capacity long-distance transmission has become a trend; and DC transmission can achieve energy decoupling across regions and other advantages , which is more conducive to application than AC transmission. [0003] As the key core equipment of the DC boost collection technology, the high-power high-boost ratio DC converter is responsible for collecting the input DC power to the high-voltage DC bus. In the prior art, there is a kind of DC converter. Each module in the N groups of fan power generation modules is...
