Description of the invention: [Technical field to which the invention pertains] In particular, a power supply having multiple power outputs is provided. The present invention relates to a power supply device. [Prior Art] It is very common to use electronic and computer products. Among them, the application of LCD screens is more and more, especially in the case of LCD screen technology, the requirements of consumers are further improved. This makes manufacturers and R&D personnel pay more attention to the tactics of multi-wei and power-saving, so that they are better competitive in the market. Please refer to Taiwan Public Patent No. 200534569, which reveals two kinds of existing driving circuits 'the first kind. The crane is directly supplied by the power source to the power supply to the power supply, and then the power supply is used for the charm. The power supply to the reverse flow ^ after the boost operation to output the high-voltage power signal 'the existing power supply in the processing of the power source output of the AC signal, including - electromagnetic dry (four) wave unit, - rectifier unit, - power factor correction - a conversion unit, which is connected to the (four) AC power by the electromagnetic dry chopping unit () and the rectifying unit, and after the transition wave and rectification processing, the iii-full/nuclear direct current signal is transmitted, and then the whole axis/half-wave direct signal is received by the electrotropin-corrected stomach. After the power factor is output, the power is shouted to the transfer element (DC_DC), and the power signal is received by the conversion unit, and then the power is exchanged and outputted - the power is turned to the reverse flow ^, and the inverter is boosted to high voltage power. The load from the signal to the backend link. Another type of driving f road 'and the aforementioned driving circuit is not _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ Waves are not good, this is the medium voltage power signal (for example, the power source is the V, then the full/half wave is directly), and the medium voltage power signal is directly boosted after the inverter. And output a high voltage power signal to the load. However, the above-mentioned conventional driving circuit is applied to a flat panel display, and only a high-voltage power signal can be separately provided to the CCFL of the cold cathode tube. Therefore, the display of the forest society cannot add an additional port for the user to insert. Pick up the required perimeters, such as: potential bars, small lights, and even 3C products that can sense the effects of image changes. Therefore, if a power supply device with multiple power outputs (including healthy DC power signals) can be provided, and the application of 5 200810333 to the (4) domain will make the audio design more profitable. 4 broken industry [invention content] ^ the purpose of the purpose - to provide a kind of multi-electrical output of the electric secret device 2 output to what contains - high voltage and low low standing power signal, to achieve the difference between the two According to the purpose of the disclosure, the feasible technical solution disclosed by the present invention comprises: - the electroacupuncture unit (10) 〇 and the - green unit of the number: - the Weibo bile flow processing half-wave pulse DC job, to the - reflux device Boost to output - high voltage power signal 1 - load, the present invention has - receive full / half wave pulse DC DC voltage = 'and after step down output - low voltage power signal to - second load, In this way, the supply and output of the wire can be provided, which is more flexible and efficient in the power supply, and can be applied to the display to provide the display with an additional low-voltage DC connection. [Embodiment] ^ 2 The detailed outline of the present invention The pumping capacity is now described as follows: = Refer to the "Figure 1", which is a block diagram of a circuit according to a preferred embodiment of the present invention. As shown in the figure, the power supply device with f power output is powered by Source iG (which can be the mains) Office: Two: Electricity The subtractive circuit system 20 and a low voltage circuit system 3, which is external to the intermediate voltage circuit system 20, respectively drive a first load 4G and a second load %. 21, FIG. 2, the medium voltage circuit system 2A has an electromagnetic interference filtering unit, a "" 'stage unit 22, a power factor corrector 23, and a inverter 24 for outputting a ^ The power signal is sent to the first load 5〇, the first load 50 can be a cold cathode lamp tube (CCFL), the second circuit, the system 3G has - electromagnetic interference filter, wave unit 3 - rectification unit %, and The early load 33 is used to output a low voltage power signal to the second load (10), and the second load port may be a static A, a light fixture, or other various 3C products. More specifically, the driving circuit of the present invention comprises: - a power source 1G, which provides an alternating current signal, the power source 1G can be a commercial power source, and the output power specification is in accordance with national power specifications (for example, or 22 〇 v); The private magnetic interference filtering unit 兀 2 卜 3 卜 and the rectifying unit of the diode bridge rectifier ^, 6 200810333 32 2 the above-mentioned electric oblique disturbance unit 2 ii rectification unit 22 and electricity, f wave and M processing and output - a full companion ship DC signal; η-, =: 4 'which may be - a piezoelectric inverter ' receives the full / half wave pulse DC signal, reads the high dust power signal to a first load 40, wherein The rectifying unit 22 is different from the one. According to the national environmental protection regulations. One receives the full/half wave pulse DC signal flow crying 24,23: The full/half wave pulse DC signal! The tiger performs voltage conversion and then inputs to the reverse phase °°, °^ Improve the harmonic distortion and phase deviation and other issues; full / half, ^ τ Λ ^ 33 ' rhyme flow change element 33 for the - drop | type cage, is to receive the π. + Wave pulse straight k «, and carry out down-woven output __ low-voltage power signal to - second load electric early, 21, 31, and rectification unit 22, 32, can also be integrated into - electromagnetic dry H skin early 21a And the rectifying unit 22a, which is further controlled by the == power factor corrector 23, depending on whether it is provided = 兀33, can effectively neutralize the components of the driving circuit.
