Description
Technical field
The present invention relates to a kind of frequency conversion speed-adjusting system, particularly relate to a kind of three phase mains with rectifying and voltage-stabilizing function, belong to variable frequency regulating speed control field.
Background technology
At present, three-phase Passive Power factor correction is applied in three phase mains harmonic management.The passive PFC of three-phase mainly three phase mains R, S, T respectively mutually in parallel or in series special parameter L-C circuit mode process three phase mains harmonic problem.Three phase mains R, S, T respectively mutually in special parameter L-C circuit mode in parallel or in series so that the current phase offset of each phase current so that electric current and voltage in phase, to improve power factor.The inductance volume that the above-mentioned shortcoming to three phase mains harmonic management is L-C circuit is big, and its parameter is determined by load, once it is determined that, it being difficult to amendment, and power factor is relatively low, part times harmonic is more difficult to be passed through.
In general, the number of phases is more many, using the teaching of the invention it is possible to provide electric current more big.One phase is about provided that the electric current of 30A～80A, the biphase electric current providing for 60A～160A.Owing to now new power consumption of processing unit is increasing, the demand of electric current is just more and more higher, so main board power supply part is also just more and more exquisite.But solving current problems can also use the magnitude of current increasing phase road to solve, and will use the good electric elements of mass ratio as some famous brand mainboards when design power supply circuits, the instability of CPU working environment so will not be caused because electric current becomes big.Certainly, it is however generally that, same brand, what the power supply number of phases was many should be better than few, and the cost of the more many manufactures of the number of phases can be more high after all.
The design that eight phases are powered can provide more stable CPU voltage and purer electric current really, and its result is exactly that CPU can surpass higher frequency under relatively low CPU voltage.This result is it can be appreciated that and confirmed by the test of numerous media and user.
For overclocking person, can improve overclocking probalility of success to CPU pressurization, strengthen job stability is almost a law, and this is a kind of illusion in fact, and the probability that the more high CPU computing of voltage makes mistakes is more big, high voltage limit overclocking is generally all only capable of running SuperPi, it is impossible to long-time steady operation.What therefore more overclocking player paid close attention to is exactly how many CPU can surpass in non-pressurized situation, or how high can surpass when adding a little voltage；So-called superfine product is greatly all referring to the CPU that can surpass upper frequency under low pressure.But when CPU body constitution is certain, the mainboard of one piece of heterogeneous power supply just can be easier to allow it reach the purpose of low-voltage high-frequency.
Such as application number is a kind of three phase mains of " 201310560315.7 ", comprising: principal phase controls module, it is based on Analog Circuit Design, it is used for exporting first phase voltage and second phase voltage, it includes input, first-phase outfan, second-phase outfan and the first exit, input connects power supply, first-phase outfan output first phase voltage, second-phase outfan output second phase voltage；And parafacies controls module, it is based on Analog Circuit Design, it includes third phase outfan, it connects principal phase and controls the first-phase outfan of module, second-phase outfan and the first exit, first phase voltage and second phase voltage that principal phase controls module output carry out phase shift, third phase outfan output third phase voltage.Produced High-frequency Interference when this three phase mains can overcome employing PWM to control.
And for example application number is a kind of three phase mains phase interruption testing device of " 201410026370.2 ", by the adhesive of relay and release conditions output detections result, adopting the rectified power supply of three phase mains, namely its power circuit itself constitutes the detection function to phase and phase generation open phase fault.The detection of phase is adopted the testing circuit based on optocoupler application technology, is made up of the half-wave rectifying circuit of three phase mains commutation diode, current-limiting resistance filter capacitor；The input light emitting diode of optocoupler accesses half-wave rectifying circuit through input resistance, and its output bidirectional triode thyristor Series Sheet commutating phase bridges into three phase mains, is realized the control of relay adhesive and release by the break-make controlled.This testing circuit brief and practical, the circuit components quantity of detecting device is few, and cost performance is higher.
