Abstract

A planar transformer comprises a primary winding, an inner insulator forming the primary winding therein, a secondary winding disposed on a vertical outer surface of the inner insulator, and an outerinsulator for integrating the secondary winding and the inner insulator as a whole. The primary winding, the inner insulator, the secondary winding and the outer insulator are provided with magnetic core holes; the primary winding is provided with a printed circuit arranged around the magnetic core holes; the secondary winding is a copper bar structure formed by stamping a copper material; the secondary winding is arranged around the magnetic core holes; and a magnetic core is installed in the magnetic core hole. The planar transformer has good performance and is low-cost.

Description

technical field [0001] The present application relates to the field of transformers, in particular to a flat-panel transformer and a manufacturing method thereof. Background technique [0002] Flat-panel transformers have low DC copper resistance, low leakage inductance and distributed capacitance, and are widely used to meet the design requirements of resonant circuits; and flat-panel transformers also have good magnetic shielding and can effectively suppress radio frequency interference, which can be used in High frequency power field. [0003] Existing planar transformers are generally formed by stacking multiple printed circuit boards, and generally adopt an assembled structure. However, the cost of printed circuit boards is relatively high, and the assembly structure of components is fixed by structures such as buckles, and the structural integrity is not stable enough and relatively loose. Contents of the invention [0004] In view of this, it is necessary to provi...
