Problems solved by technology

[0004] At present, when winding the magnetic core in the PFC coil device, it is first necessary to inject the winding skeleton into the shape of the magnetic core, and then carry out integral winding. Since there are many shapes of the magnetic core, it is impossible to use all magnetic cores. For example, when winding a U-shaped magnetic core, manual winding is required to ensure the neatness of the winding, but the strength of manual winding is not easy to control, resulting in unstable winding structure and costly A lot of labor and time, and the existing PFC uses epoxy resin or adhesive tape to assemble the upper and lower magnetic cores. The manufacturing process is complicated. Although the wrapping is good, the heat dissipation is not good.

Description

technical field [0001] The invention relates to the technical field of PFC coil devices, in particular to a PFC coil device and a use method. Background technique [0002] PFC means "power factor correction". Power factor refers to the relationship between effective power and total power consumption (apparent power), that is, the ratio of effective power divided by total power consumption (apparent power). Basically, the power factor can measure the degree to which electricity is effectively utilized. When the value of the power factor is larger, it means that the power utilization rate is higher. Power factor is a parameter used to measure the power efficiency of electrical equipment, and low power factor represents low power efficiency. The technology to improve the power factor of electrical equipment is called power factor correction. [0003] There are two types of PFC at present, one is passive PFC (also called passive PFC) and active PFC (also called active PFC). P...
