Reversed phase converter

Abstract

The present invention relates to an inverting converter, the structure of which includes a first winding tube, a plurality of second winding tubes, a first magnetic core and a second magnetic core, wherein the first winding tube and the plurality of second winding tubes The coils are stacked and combined with the first and second magnetic cores to form at least a closed magnetic circuit; in addition, the first coil is provided with a hub where a primary coil can be wound horizontally to increase the primary The winding space of the winding is perpendicular to the winding direction of the secondary winding provided by the second winding tube, so that the high temperature generated by the primary winding can be effectively reduced and the length of the magnetic core can be shortened.

Description

technical field [0001] The invention relates to an inverting converter, in particular to an inverting converter which can generate multiple high-voltage sides to provide a corresponding number of cold cathode tubes. Background technique [0002] It is known that a general inverting converter is to put a magnetic core in a winding shaft, and then wind the coils with the same or different wire diameters on the winding shaft to form a primary side coil and a secondary side coil. The primary side coil and the secondary side coil are then covered with a casing, so that an inverting converter of an induction coil can be formed; and the backlight module (Back LightModule) used for lighting in today's liquid crystal display (LCD) The high-efficiency and light-weight cold-cathode fluorescent lamp (CCFL) used needs to be driven by high-voltage power, so an inverting converter must be used to make the cold-cathode fluorescent lamp (CCFL) emit light and form a liquid crystal Light sour...

Problems solved by technology

[0004] It can be seen from the above that if high voltage is to be generated, the number of coils in the primary side winding area must be increased, but the space on both sides of the primary side winding area is squeezed by the secondary side winding area to limit the range, so that the coils can only be stacked upwards. , It will also cause difficulty in assembling on the circuit board, and it will easily lead to the problem of overheating the temperature of the inverting converter. However, the winding space in the primary side winding area is limited, and reducing the number of coils that can be wound will inevitably affect the voltage output of the inverting transformer, so the cold cathode fluorescent tubes that can be configured are also limited. limit

[0005] Furthermore, if the length of the primary side winding area is increased to increase the number of winding coils, a longer magnetic core must be configured, and a certain quality cannot be produced for this magnetic core, which will inevitably affect the efficiency of the inverting converter

[0006] It can be seen that the above-mentioned existing inverting converter obviously still has inconvenience and defects in structure and use, and needs to be further improved urgently.

In order to solve the problems of inverting converters, relevant manufacturers have tried their best to find a solution, but no suitable design has been developed for a long time, and general products do not have a suitable structure to solve the above problems. Obviously, it is a problem that relevant industry players are eager to solve.
