Abstract
The invention relates to a component of wind power generation equipment, and in particular relates to an insulated gate bipolar transistor (IGBT) module formed by double-parallel transistor units for a wind power converter. The IGBT module comprises three pairs of upper IGBT units and lower IGBT units between a three-phase alternating current end and direct current positive and negative electrodes, wherein each upper IGBT unit and each lower IGBT unit are respectively formed by two same IGBTs connected in parallel. The IGBT module provided by the invention has the advantages that as the upper IGBT units and the lower IGBT units are respectively formed by IGBTs connected in parallel, higher current density is provided, and therefore not only is relatively high cost performance achieved, but also uniform thermal distribution can be realized, the component life is prolonged, and the operational reliability is improved; and the drive circuit of the grid is designed such that the IGBTs connected in parallel use a same driver, and the drive circuit is in full symmetry, therefore the transmission delay difference across the drive circuit is reduced, and relatively good dynamic flow equalization is achieved.
Description
Technical field
The present invention relates to the wind power plant parts, specifically is a kind of two-tube parallelly connected unit wind electric converter IBGT module.
Background technology
Current transformer in the wind power plant is to be connected being used between generator and the electrical network electric energy that wind power generation produces is carried out conversion, so that its equipment that satisfies the requirement of electric power conveying and output to electrical network.The IGBT module is the core component of current transformer rectification and inversion; In traditional technology; The IGBT module is shown in accompanying drawing 1; Three pairs go up pipe IGBT unit and down pipe IBGT unit be connected between A, B, C three-phase alternating current end and direct-flow positive pole, the negative pole, pipe and following pipe unit all are that the single IGBT of employing carries out rectification and inversion it on.This scheme can't be accomplished desirable situation for current density, Homogeneouslly-radiating etc., and the current class of IGBT is generally all bigger in therefore traditional wind electric converter, and not only the element cost is higher for it, and the local pyrexia amount is big, influences element useful life.
Summary of the invention
Technical problem to be solved by this invention is that a kind of even, reliable two-tube parallelly connected unit wind electric converter IBGT module of components and parts cost, element heating that can reduce wind-powered electricity generation for the stream device is provided.
Two-tube parallelly connected unit of the present invention wind electric converter IBGT module includes on three couple between three-phase alternating current end and the direct current both positive and negative polarity pipe IBGT unit and pipe IGBT unit down, said each go up pipe IGBT unit and be formed in parallel by two identical IGBT with the following IGBT of pipe unit.
Two IGBT of said parallel connection are by same driving circuit drives; Resistance in the driving loop of each IGBT is divided into two parts; A part is the resistance R g that is connected grid one side; Another part is the resistance R e that is connected emitter one side, and resistance R g is 2:1 with the ratio of the resistance of resistance R e.
The present invention adopts pipe IGBT unit and following pipe IGBT unit on the parallelly connected IBGT formation, and higher current density can be provided, and not only has high cost performance, and evenly heat distribution, prolongs component life; Improve its operational reliability; The design in the driving loop of grid makes parallel IGBT adopt same driver, drives loop symmetry fully, and it is poor to have reduced the transmission delay that drives between the loop, has realized the better dynamic current-sharing; Particularly resistance is arranged according to specific ratio branch; Make that the tolerance of electric capacity is enough little between 2/3 resistance Rg and grid and the emitter; And remaining 1/3 resistance Re can reduce because the power change of current loop asymmetric dynamic current that causes of stray inductance is unbalanced, has improved the operational reliability of module.
