Push-pull transformer based on electronic circuit board PCB and processing technology of push-pull transformer

Abstract

The invention discloses a push-pull transformer based on an electronic circuit board PCB and a processing technology of the push-pull transformer. The transformer comprises a transformer shell; a PCBdisposed in the transformer shell; a first coil which is arranged on the upper end face of the PCB, a plurality of coils which are arranged on a middle layer, and a second coil arranged on the lower end face; a first magnetic core which is clamped with the upper end surface of the PCB; a second magnetic core which is clamped with the lower end surface of the PCB; four pins which are arranged on the PCB; a first controller which is arranged on the upper end surface of the PCB; a first diode which is arranged on the upper end surface of the PCB; a second controller which is arranged on the lowerend surface of the PCB; a second diode which is arranged on the lower end surface of the PCB; and a plurality of capacitors which are arranged on the upper end surface and the lower end surface of the PCB. A transformer winding is replaced by an electronic circuit board PCB copper wire, the transformer winding is integrated and distributed in the electronic circuit board PCB, manual winding is not needed any more, and high production consistency and reliability are kept. Moreover, the transformer is simple to manufacture and low in cost.

Description

technical field [0001] The invention relates to the technical field of transformers, in particular to a push-pull transformer based on an electronic circuit board PCB and a processing technology thereof. Background technique [0002] At present, 1-3 watts of micro-power isolated power supply adopts such as figure 1 shown in the self-excited push-pull, as figure 2 In the other push-pull designs shown, the push-pull transformer used for isolation uses the enameled wire winding process, and its manufacture is very complicated, mainly having the following defects: [0003] 1) Transformer enameled wire has many windings, many turns, manual winding is difficult, machine winding cost is high, and machine maintenance is difficult; [0004] 2) When processing transformers, due to human participation, large parameter deviations, error-prone, poor consistency, and bad batches exist); [0005] 3) There are many types of enameled wires used in transformers, which are difficult to man...
