Description

A fast charger transformer

technical field

The invention relates to the technical field of transformers, in particular to a fast charger transformer.

Background technique

The characteristics of planar transformers are high frequency, low shape, small height and high operating frequency. Compared with traditional transformers, the biggest difference between planar transformers is the iron core and coil windings. Toroidal ferrite core, usually made of high-frequency power ferrite material, has low core loss at high frequency; the winding is made of multilayer printed circuit boards, and the windings or copper sheets are stacked. The magnetic circuit of the transformer is formed on the flat high-frequency iron core. This design has low DC copper resistance, low leakage inductance and distributed capacitance, which can meet the design requirements of the resonant circuit. Suppress radio frequency interference.

However, the planar transformer does not have the function of efficient heat dissipation. During the operation of the planar transformer, it is difficult to avoid no-load loss and load loss. These losses will accumulate on the windings, magnetic cores and structural parts of the transformer in the form of heat, making the windings, magnetic The temperature of the core and its surrounding medium rises, and the long-term use will easily lead to thermal damage to the planar transformer, which in turn affects the normal use of the planar transformer.
