Site preparation describes, it is clear that described embodiment is the part of the embodiment of the present invention, rather than whole embodiments.Based on this hair
Embodiment in bright, the every other reality that those of ordinary skill in the art are obtained on the premise of creative work is not made
Example is applied, should all belong to the scope of protection of the invention.
A kind of design for optimizing inverter internal layout, including the design of full aluminium fuselage and internal functional elements are including following
Several parts：
1) structure design；The structure design of the design is full aluminium fuselage, is divided into lid, housing and radiator, the mistake of assembling
Cheng Zhongxian is radiator and housing screw connection, when internal circuit board and cabling scheduling and planning are completed, with lid on key screw and
Housing connects, and installation is simple, small volume, full aluminium fuselage, and body weight is light.
2) component placement；The components' placement of the design is using compact layout designs and is easy to the layout of wiring to set
Meter.
3) board layout；The wiring board design of the design is divided into power cell, control unit, display unit and power supply list
Member.Power cell includes direct current plate, inversion plate and exchanges plate.The such maintenance being designed with beneficial to the later stage and the analysis of problem.
4)；Cabling is laid out；The cabling of the design avoids the cabling design of power device using connecting nearby.It is such
Design is readily produced installation, also strengthens the stability and reliability of inverter.
The design principle of the present invention is specific as follows：
Inverter is the equipment for direct current being transformed into alternating current, is divided into direct current component, Converting Unit with exchange portion
Point, the design is divided into power cell, control unit, power subsystem and display unit according to this division wiring board design, wiring board.
Power cell is divided into direct current component, Converting Unit and AC portion, and the effect of direct current component is that DC voltage is increased to bus
