Problems solved by technology

Due to the requirements of the frequency range of the EMC circuit, it is difficult to make the volume small. In order to enhance the filtering effect, the filter inductor usually uses a ring inductor with complex winding, which will make it difficult to reduce the cost and make the volume difficult.
Therefore, the EMC filter circuit in the existing power module products usually accounts for about one-fifth to one-half of the volume of the entire power module, and the cost usually accounts for about one-tenth to one-third, especially for the secondary power supply. The EMC filter circuit configured around the module is sometimes larger than the power module itself

Description

technical field [0001] The invention belongs to the technical field of automatic control, more specifically, it belongs to a dimming control device for semiconductor lighting. Background technique [0002] LED lighting technology has incomparable advantages over traditional lighting technology, and now it has been widely used. LED lighting fixtures have the advantages of high luminous flux and low power consumption. The medium and small power LED lighting fixtures in the prior art need to be equipped with an AC-to-DC power supply, and LED lighting fixtures usually need to be equipped with a DC power supply. How to effectively control the DC power supply is a difficult problem restricting the technical field. [0003] At present, the electromagnetic compatibility problem of LED lighting power supply is becoming more and more prominent, especially the conduction emission and radiation emission of electronic equipment directly affect people's health, so the EMC requirements fo...
