Abstract

The invention discloses an intelligent regulation and control power terminal connector which comprises a shell, a middle supporting plate, a positive plate, a negative plate, miniature electric push rods, an insulating column, a diversion reinforcing column, an inductance detector and a relay. When the diversion reinforcing columns are inserted into the outer sides of the anode terminal and the cathode terminal of the power terminal in the prior art, not only can the firmness be improved, but also the electrical connection range can be enhanced by means of the diversion reinforcing columns, and the purposes of increasing the power and improving the electrical transmission effect are achieved; the positive plate and the negative plate can be fixed and isolated, stray inductance is effectively reduced, the inductance detector can detect inductance and electromagnetic states in real time, the relay can control a switch, and switching adjustment is facilitated.

Description

technical field [0001] The invention relates to the technical field of electrical connectors, in particular to an intelligent control power terminal connector. Background technique [0002] High-power converters are more and more widely used in rail transit, industrial converters, new energy and other fields. The shorter and shorter switching time of the power semiconductor chip IGBT used in it leads to excessively high dv / dt and di / dt. Moreover, the stray inductance of the DC link will cause overvoltage when the IGBT is turned off. This overvoltage plus the DC bus voltage may cause Vce>Vce(Max). Overvoltage may damage the IGBT chip, which will cause distributed stray inductance to have a more important impact on the turn-off characteristics of power devices. In order to eliminate the impact of this stray inductance on high-power devices, especially high-power-density modules, laminated power terminal (Laminated Busbar) technology can be used to suppress IGBT overvolta...
