Abstract
The utility model provides a solar inverter, comprising at least one solar inverter module; the solar inverter module comprises a case, an insulating gate bipolar transistor module, a control board, a capacitor bank, an inductor and the like. A plurality of the solar inverter modules can form the solar inverter through parallel connection, when one or a plurality of solar inverter modules has/have faults in the operating process of the solar inverter, other solar inverter modules can run normally, so that the whole solar inverter can run continuously, therefore, the solar inverter has high reliability; moreover, the quantity of the solar inverter modules can be increased or reduced conveniently according to the practical using requirements, therefore, the solar inverter module has good generality.
Description
Technical field
The utility model relates to a kind of solar inverter.
Background technology
At present, the design that is integrated of big-power solar inverter, complete machine can not be worked when the critical piece inversion unit breaks down, and causes its reliability not high.And, need the expert engineer to go to scene or complete machine to retract maintenance during maintenance, time-consuming and effort.Simultaneously, along with the continuous increase of power, power device type selecting and buying are subjected to certain restriction, thereby, need a kind of modularized design to avoid this problem.
The utility model content
Technical problem to be solved in the utility model is to provide the solar inverter that a kind of reliability is high and be convenient to keep in repair.
The utility model is achieved in that a kind of solar inverter, and it comprises at least one solar inverter module.Described solar inverter module comprises a cabinet, an insulated gate bipolar transistor module, a control board, a capacitance group, reaches an inductor; Described insulated gate bipolar transistor module, described control board, described capacitance group, and described inductor be arranged in the described cabinet.
Further, described solar inverter comprises some described solar inverter modules, and described solar inverter module can parallel with one anotherly connect.
Further, described insulated gate bipolar transistor module comprises an insulated gate bipolar transistor and a radiator.
Further, on the described cabinet plurality of fans is installed; The corresponding setting of described insulated gate bipolar transistor module with one of described fan.
Further, described control board is the Digital Signal Processing control chip.
Further, described inductor is the amorphous inductance.
Further, hot-plug interface and hot plug inserting terminal further are set on the described cabinet.
Compared with prior art, solar inverter module of the present utility model can solar inverter of a plurality of one-tenth parallel with one another, in the solar inverter running, when if one or several solar inverter module breaks down, other solar inverter module can normally be moved, can not make whole solar inverter out of service, thereby can make solar inverter have higher reliability.And each solar inverter module has hot plug performance preferably, thereby can shorten greatly and install and maintenance time.In addition, can increase or reduce the quantity of solar inverter module easily, make the solar inverter module have good versatility according to the demand of reality use.
