Problems solved by technology

In this case, the power board suppliers are often unwilling to modify the standard design of the power board for a single customer, and can only rely on the customer to solve it by themselves, and the power board supplier is also unwilling to disclose the detailed design of the power board, thus This increases the difficulty of product testing EMC and increases the cost of solving problems

Abstract

The invention discloses an EMC debugging filter board card of electronic equipment and a debugging method. The filter board card comprises at least two filter modules, the at least two filter modules are in cascade connection, each filter module is correspondingly provided with a short circuit, and the short circuit is used for controlling the corresponding filter module to stop working or work. Therefore, by selecting a proper filter module combination on the filter board card, most EMC problems caused by power supply noise can be quickly solved under the condition that a standard power supply board card is not modified, so that the cost for solving the problems can be reduced.

Description

technical field [0001] The invention relates to the technical field of electronic equipment, in particular to an EMC debugging filter board and a debugging method for electronic equipment. Background technique [0002] At present, the power main boards of many high-power devices are independent standard boards (referred to as power boards). Since power boards are standard products, in most cases the EMC (Electro Magnetic Compatibility, electromagnetic compatibility) of the power board itself is It meets the requirements, but when the product is tested for EMC, the status of the whole machine may exceed the standard due to the overall layout or external load. In this case, the power board suppliers are often unwilling to modify the standard design of the power board for a single customer, and can only rely on the customer to solve it by themselves, and the power board supplier is also unwilling to disclose the detailed design of the power board, thus This increases the diffi...
