Embodiment Construction

[0025] like figure 1 and figure 2 As shown, an embodiment of the present invention includes a control chip and a main circuit unit. The main circuit unit includes a low-voltage capacitor branch and eight Power MOSFETs. The eight Power MOSFETs are connected in series to form four series branches. The four The series branch is connected in parallel, the low-voltage capacitor branch is connected in parallel with the series branch, and the gate of the Power MOSFET is connected to the control chip.

[0026] The control chip can choose any one of CPLD, FPGA, DSP, ARM, POWERPC, etc. The control chip used in the present invention is FPGA, and its model is: XC3S700AN-4FG484I. The communication interface of the control chip can receive external control commands and be analyzed and processed by the control chip. The control commands include which state each Power MOSFET will enter: normal, forced on, and forced off. The form of the communication interface can be any one of RS232, RS4...

Abstract

The invention discloses an emulation device and method for a converter module. The emulation device for the converter module comprises a control chip and a main circuit unit, wherein the main circuit unit comprises a low voltage capacitance sub-circuit and eight PowerMOSFETs (Metal-Oxide-Semiconductor Field Effect Transistors); every two PowerMOSFETs are connected in series to form a series sub-circuit, so that four series sub-circuits are formed; the four series sub-circuits are connected in parallel; the low voltage capacitance sub-circuit is connected with the series sub-circuits in parallel; and grids of the PowerMOSFETs are accessed into the control chip. The volume of the emulation device is reduced to one-tenth of that of the original converter module; the cost is reduced to hundredth of that of the original converter module; and the weight is reduced to fiftieth of that of the original. The emulation device can acquire normal information and failure information of various types conveniently and flexibly; and great convenience is brought to an early-stage study of a control circuit part of a converter, debugging of software and hardware, research and development as well as verification of a testing device for the converter module.

Description

technical field [0001] The invention relates to a converter module, in particular to a converter module simulation device and a simulation method. Background technique [0002] Converters include main traction inverters, auxiliary inverters, etc., which are high-power electrical equipment used in locomotives, bullet trains, high-speed rail, and subway vehicles. Taking the main traction inverter on a locomotive as an example, when it is working normally, the input rated voltage is DC1500V (fluctuation range is between DC1050V~DC1875V), and the output is 0V~1400V, 800A three-phase AC. The interior of the converter generally includes a control circuit part and a main circuit part. The converter module is a part of the main circuit, which includes an inverter part consisting of six switching tubes, a chopper part consisting of two switching tubes, and a supporting capacitor. The control circuit part (such as: DCU) needs to be jointly debugged with the converter module during t...
