Abstract
The utility model discloses an inverter module with low line inductance. The inverter module with low line inductance comprises a support, a U-shaped composite busbar fixed on the support, a plurality of straightly-arranged filter capacitors installed on one side face of the U-shaped composite busbar, clamp diodes and insulated gate bipolar translators (IGBTs), wherein IGBT driving boxes used for driving the IGBTs are installed on another side face of the U-shaped composite busbar, and IGBT driving plates which are connected with the IGBTs and have the same number as the IGBTs are installed in the IGBTs driving boxes. With reasonable arrangement of components of an inversion assembly, the area encircled by a conversion current loop generated by the components is reduced at the utmost, the line inductance is thus lowered, and system safety is greatly enhanced without raising costs.
Description
Technical field
The utility model relates to frequency converter field, relates in particular to a kind of inverter module of low line inductance.
Background technology
Along with China is actively pushing forward industrialization and modernization energy innovation system, energy development faces severe form and challenge.Frequency control has become an energy-conservation important disseminate technology, and frequency converter is to utilize the effect that turns on and off of semiconductor power device that power frequency supply is transformed to the adjustable electrical energy changer of frequency.
Inverter module is as the important component part of frequency converter, and its effect is the adjustable AC power of input DC power output frequency.
Each device of inversion module is aspect Position Design, if having formed closed loop, the position of each device can produce line inductance, along with the increase of line inductance can cause power device IGBT shutoff voltage higher, even exceed bearing of IGBT, thereby burn device, security of system is reduced greatly.Each device of inversion module at present, owing to installing or user's request, on location layout, each device easily forms loop conventionally.For inverter assembly, the layout of structure is unreasonable is the main cause that causes line inductance.
Utility model content
The utility model object is to overcome prior art defect, and a kind of inverter module of low line inductance is provided, to solve the bad problem of frequency convertor system fail safe.
For achieving the above object, the utility model adopts following scheme:
The inverter module of low line inductance, comprise support, be fixed on the U-shaped composite bus bar on support, be arranged on multiple filter capacitors, clamping diode and the IGBT of word order on side of U-shaped composite bus bar, the IGBT that U-shaped composite bus bar another side is provided with for driving IGBT drives box, and the identical IGBT drive plate of quantity connecting with described IGBT is installed in IGBT driving box.
Described filter capacitor is divided into two groups and is fixed on support, and cooled plate is also installed on support, and two groups of filter capacitors, clamping diode and IGBT are bolted in cooled plate.
The described fan that heat radiation is installed between two groups of filter capacitors.
The inversion module left and right sides is provided with the handle of convenient carrying.
The sliding rail groove of being convenient to installation is arranged at inversion module bottom.
Compared with prior art, multiple filter capacitors, clamping diode and the IGBT of the utility model composition inverter module are word order, maximum possible dwindle the area that inversion assembly commutation circuit surrounds, thereby attenuating line inductance, thereby under the prerequisite that does not increase cost, greatly strengthen the fail safe of system.
Further, on inversion module, there are handle and the convenient sliding rail of installing of convenient carrying, thereby improve the ease for use of product.
