Background technology

All it is to realize the parameter of requirement using an inductance and a transformer in present actual LLC circuits.Disadvantage It is that transformer needs an external inductor, transformer needs to be used in series with inductor, volume relative same frequency, identical work( Rate equipment is larger, and processing technology is complicated, and cost can improve 15% ~ 20%.Currently, due to market to Switch Power Transformer from body Product, more stringent requirements are proposed for performance, it is therefore desirable to novel transformer and corresponding processing technology is developed, to meet market Demand.

Invention content

In view of the deficiencies in the prior art and the market demand, the utility model provides a kind of integrated transformation of PQ types high-frequency and high-voltage Device, by circuit inductor and transformer integrate, it is non-overlapping by the completely separable coiling of the primary and secondary of transformer, make The primary and secondary degree that intercouples mutually is on duty, and the interelectrode capacity between winding is reduced with this, reduces noise in circuit and output It is unstable.By adjusting the air gap of inductance part, the leakage inductance of transformer can be effectively controlled, and leakage inductance is allowed to be maintained at certain model In enclosing, adopt the technical scheme that, a kind of PQ types high-frequency and high-voltage integrated transformer, including PQ types inductance framework, PQ type transformers Skeleton, PQ inductance cores, PQ magnetic core of transformers, terminal, inductor winding, primary winding, transformer secondary output winding, it is special Sign is：PQ types inductance framework is linked into an integrated entity with PQ types transformer framework by inductor winding and transformer winding connecting line, The inductor winding being coiled into is arranged in the three-layer insulated twisted wire of the useful Kapton of PQ type inductance frameworks, inductor winding plays termination end Son, tail end are simultaneously the origin or beginning of primary winding, and the useful Kapton of PQ type transformer frameworks is three-layer insulated twisted Line arranges the primary winding being coiled into, tail end connecting terminal, in the useful Kapton in primary winding outer surface Three-layer insulated twisted wire arranges the transformer secondary output winding being coiled into, and rises, tail end connecting terminal, two pieces of PQ type magnetic core of transformers are mounted on On PQ type transformer frameworks, functional surfaces are bonded together using anaerobic adhesive, and PQ type inductance cores are mounted on PQ type inductance frameworks, Functional surfaces are bonded in two pieces of PQ type magnetic core of transformers sides, dipping lacquer and drying using anaerobic adhesive.

The three-layer insulated twisted wire of the Kapton is thin by insulating twisted line outer surface three strata acid imides of package Film is constituted.

The inductor winding origin or beginning, primary winding tail end, transformer secondary output winding rise, tail end, uses electric resistance welding Pick solder terminal.

The utility model has the beneficial effects that circuit is simple, small, insulating properties, connection reliability are high, processing technology letter Change, production efficiency it is high, greatly reduce cost of labor and material cost, reduce the unstable of noise in circuit and output, Solve skin effect and closing effect, to meet high-quality of the market to LLC circuit medium-high frequency high voltage power transformers Demand.
