Abstract
The invention discloses a testing platform for a three-level H bridge converter. The testing platform comprises two tested three-level modules, a voltage regulator, a rectifier bridge, an electric reactor, a current Hall device, a testing control panel and a human-computer interface. A direct-current bus of the first tested three-level module is connected with the direct-current output of the rectifier bridge, the alternating-current outgoing line O1of the first tested three-level module is connected with one end of the electric reactor, and the other end of the electric reactor penetrates through the current Hall device and is connected with the alternating-current outgoing line O2 of the second tested three-level module; the alternating-current outgoing line O1 of the second tested three-level module is connected with the alternating-current outgoing line O2 of the first tested three-level module; the current Hall device is further connected with the testing control panel, and the testing control panel is connected with the two tested three-level modules through two sets of optical fibers. The full-load operating state of the converter and the operating characteristic of the converter under the limiting circumstance can be tested conveniently and fast.
Description
Technical field
The present invention relates to power electronics neighborhood, more particularly, relate to a kind of test platform of three level H bridge inverter.
Background technology
The progress of Adjoint technology, is widely applied in transmission and distribution networks by the power electronic equipment of three level H bridge topology formation, and the electric pressure and the capacity that form the power model of these equipment are also increasing.Test power model being carried out to rated capacity and performance is also more and more difficult.Conveniently test the performance of three level H bridge inverter, and reduce testing cost, therefore, market is badly in need of a kind of test platform for three level H bridge inverter.
Summary of the invention
For the defect existed in prior art, the object of this invention is to provide a kind of test platform of three level H bridge inverter.
For achieving the above object, the present invention adopts following technical scheme:
A test platform for three level H bridge inverter,
The man-machine interface comprising two tested three level modules, pressure regulator, rectifier bridge, reactor, current Hall, test control panel and be connected with described test control panel; The input end of described pressure regulator exchanges with 380V and is connected, and the output terminal of described pressure regulator is connected with described rectifier bridge; The DC bus of described the first tested three level module exports with the direct current of rectifier bridge and is connected; The interchange outlet O1 of described the first tested three level module is connected with one end of reactor, and the other end of reactor is connected through current Hall and with the outlet O2 that exchanges of described the second tested three level module; The interchange outlet O1 of the second three level module is connected with the outlet O2 that exchanges of described the first tested three level module; Described current Hall is also connected with test control panel; Described test control panel is connected with described two tested three level modules respectively by two groups of optical fiber.
Compared with prior art, adopt the test platform of a kind of three level H bridge inverter of the present invention, there is the operation characteristic of convenient and swift test inverter quota running status and limiting case lower device.
Accompanying drawing explanation
Fig. 1 is the principle schematic of the test platform of three level H bridge inverter of the present invention.
Embodiment
Technical scheme of the present invention is further illustrated below in conjunction with drawings and Examples.
Test platform as shown in Figure 1, comprises tested three level module M1, M2, pressure regulator TR, rectifier bridge Z1, reactor L, current Hall LEM, test control panel B1, man-machine interface H1.The DC bus of wherein tested three level module M1 exports with the direct current of rectifier bridge and is directly connected; The interchange outlet O1 of three level module M1 is connected to reactor L, and the other end of reactor is connected to the interchange outlet O2 of three level module M2 through current Hall LEM; The interchange outlet O1 of three level module M2 is directly connected to the interchange outlet O2 of three level module M1; The measuring-signal of current Hall LEM introduces the test control panel B1 of parametric controller; Test control panel B1 passes through two groups of Fiber connection to two measured power module M1, M2; Tester issues parameter by man-machine interface H1 to controller thus tests tested three level module, and parameter comprises: angle and electric current etc.
Export differential seat angle by the interchange of man-machine interface setting module DC voltage and M1, M2, make module output voltage difference form electric current on inductance.Set the size that suitable differential seat angle (such as within 5 degree) just can adjust output current, make it the test value needed.The power characteristic of power model, heat radiation and long-term oepration at full load ability can be verified by this test.
Those of ordinary skill in the art will be appreciated that, above embodiment is only used to object of the present invention is described, and be not used as limitation of the invention, as long as in essential scope of the present invention, the change of the above embodiment, modification all will be dropped in the scope of claim of the present invention.
