The invention relates to a power module signal connecting device and an implementation method therefor. The device comprises a main control board and N power modules. The N power modules comprise the first power module, the second power module,..., and the N-th power module, wherein N is a positive integer greater than one. Moreover, the main control board and the N power modules are connected sequentially. According to the invention, a problem caused by a large number of wires connected between a large power module and the main control board is solved, and multi-way drive signals outputted by the main control board are transmitted to the main circuit of the corresponding power module one by one through signal transmission units disposed on the power modules.
Description
Technical field [0001] The invention relates to the field of signal connection between high-power power supply modules in the power electronics industry, in particular to a power module signal connection device and an implementation method thereof. Background technique [0002] In the design of modern power electronic power supply systems, in order to adapt to industrial production, improve the standardization of equipment design, and reduce product production costs, the power supply system often adopts modular design. Especially in UPS, photovoltaic inverter and other systems, there are often a large number of power module units with single functions and unified interfaces that need to be electrically connected to the main control board. See the connection method of traditional power module signal line figure 1 , Because there must be a signal line connection between the power module and the main control board controller, when there are many power modules connected to the main c...
