Abstract

The utility model discloses a transformer for a power supplier, which is arranged in the power supplier and is used for the voltage conversion. The transformer for the power supplier is mainly composed of an iron core, a coil assembly for main power source, a stand-by coil assembly and a skeleton. The utility model is characterized in that: the iron core is formed with four magnetic conductive columns which extend from a base vertically. The four magnetic conductive columns are winded with the coil assembly for main power source and the stand-by coil assembly. According to the above conformation, a transformer for main power source and a stand-by transformer are integrated together in the power supplier. Thus, the effects of volume reduction, weight reduction and cost cutting can be achieved.

Description

The transformer of power supply unit

Technical field

The utility model relates to a kind of transformer, particularly a kind of transformer of the power supply unit that can reach reduced volume, weight reduction and reduce cost.

Background technology

The employed power supply unit of known host computer is combined (please refer to shown in Figure 5) by a main power circuit 2 and a standby power circuit 3, this main power circuit 2 and a standby power circuit 3 have pulse

width modulating chip

21,31 separately, this pulse width modulating chip the 21, the 31st a kind ofly can become pulse to the input voltage copped wave of transformer, by changing width, quantity or the distribution rule of pulse, reach the numerical value of change output voltage and the control method of frequency.

Above-mentioned standby power circuit 3 just has the power supply input behind the plug that plugs in, pulse width modulating chip 31 wherein can become pulse voltage with input voltage copped wave, utilizes a standby transformer 3 again.Change the magnitude of voltage of pulse voltage, change into direct voltage as the standby power that exports host computer to through over commutation and filter circuit then, make host computer be in holding state; Again, behind the mains switch of pressing host computer, its main power circuit 2 just has the power supply input, pulse width modulating chip 21 wherein can become pulse voltage with input voltage copped wave, change the magnitude of voltage of pulse voltage again with another main transformer 20, change into direct voltage as the running power supply that exports host computer to through over commutation and filter circuit then, host computer is come into operation.

Again, no matter which kind of form the transformer of known power supply unit inside is, the main core structure that all is to use a kind of three pillar type, it is by one three cylindricality iron core 70 for (please refer to shown in Figure 6), bar-shaped iron core 71, primary coil 72, secondary coil 73 and skeleton 74 combine, this iron core is to vertically extend three conducting magnetic columns 701 to form on a pedestal 711, and primary coil 72 and secondary coil 73 are set around on the skeleton 74, then this skeleton 74 is set on the conducting magnetic column 701 that is positioned at central authorities, again a bar-shaped iron core 71 is arranged at the end of three conducting magnetic columns 701, behind pulse voltage input primary coil 72, this conducting magnetic column 701 can be subjected to the induction of the pulse voltage of primary coil 72, and pulse voltage is converted to pulsed magnetic field, it makes this secondary coil 73 produce the output voltage of different numerical value by the indirect inductive secondary 73 of pulsed magnetic field.

According to above-mentioned structure as can be known, because the iron core of known transformer can only a corresponding primary coil and secondary coil, therefore its input has only a kind of transformation pattern with output voltage, it is the demand of corresponding main power circuit and standby power circuit simultaneously, provide the standby power circuit employed transformer so need one, and one provide main power circuit employed transformer, so not only make material cost increase, and reduced product competitiveness, also because taken double space, and be difficult to meet light, thin, short, the little principle of electronic product.

Summary of the invention

This case creator has the disappearance of the transformer of stating known power supply unit in view of this, and the whence studies intensively, and long-pending individual is engaged in the many years of experience of this cause, designs a kind of transformer of brand-new power supply unit eventually.

Main purpose of the present utility model aims to provide a kind of transformer of the effect that can reach reduced volume, weight reduction and reduce cost.

For reaching above-mentioned purpose, the transformer of a kind of power supply unit of the present utility model, it is mainly constructed is by one four cylindricality iron core, the main power source primary coil, the main power source secondary coil, the standby primary coil, the standby secondary coil, main coil skeleton and standby coil rack combine, it is characterized in that: this four cylindricalitys iron core is to vertically extend four conducting magnetic columns to form on a pedestal, this main power source primary coil and main power source secondary coil are to be set around on the main coil skeleton, this standby primary coil and standby secondary coil are to be set around on the standby coil rack, this main coil skeleton and standby coil rack are to be sheathed on respectively on the different conducting magnetic columns, and a bar-shaped iron core are arranged at the end of these four conducting magnetic columns.

According to above-mentioned structure, the transformer of the utility model power supply unit must be combined in one with main power transformer in the power supply unit and standby transformer, and the effect that reaches reduced volume, weight reduction and reduce cost.

Structure of the present utility model, device and feature thereof are lifted a preferable possible embodiments and a conjunction with figs. and are described in detail as follows.
