Abstract
The present invention belongs to a rectification and controllable rectification circuit capable of converting single-phase current into direct current, consisting of power supply, capacitor, inductor, transformer, rectification and controllable rectification device. It derives the advantages of convenient single-phase supply and stationary D.C. output, fewer harmonic waves and high power factor of multi-phase rectification so as to overcome some disadvantages of single-phase and multi-phase rectification circuit. It can solve the very serious problems which can be presented in single-phase rectification circuit of electronic ballast and power switch which generally use parallel capacitors to make filtration, such as large input current distortion, low power factor and their contamination, to network harmonic wave.

Description
The present invention relates to rectification and controlled rectification tandem circuit, relate in particular to the tandem circuit of single-phase ac power supply reality poly phase rectification and controlled rectification, and its application.
The number of phases branch that existing rectification circuit is powered according to power supply: two types of single phase power supply and heterogeneous power supplies are arranged, and the rectification circuit of single phase poaer supply power supply is to adopt single phase rectifier circuit.And the existing single-phase rectifier of rectification circuit of polyphase source power supply also has poly phase rectification.The single phase power supply circuit is simple, and is easy to use, be most of household electrical appliance and the extensively employing of low-power equipment institute, but the rectification circuit of existing single phase power supply output dc pulse is big, ripple frequency is low, and the Lu ripple is difficulty.When adopting the single phase rectifier circuit of simple electric capacity input Lu ripple, it can make and exchange input current waveform generation severe distortion, thereby power factor and rectification efficiency are reduced, when particularly being widely used in electric ballast and colour TV Switching Power Supply, they can produce very serious pollution to electrical network.
Polyphase source supply line complexity, power supply inconvenience, therefore be used in three-phase electricity and the bigger occasion of power more, application is seldom arranged in household electrical appliances, because the power supply of thumping majority family all has only single phase poaer supply, dc pulse is little but polyphase rectifier circuit has output, and it is also little that ripple frequency height, Lu ripple exchange the input current waveform distortion easily, a series of existing single phase rectifier circuits such as power factor height the advantage that can't compare, be not used.
Can draw the advantage of above-mentioned two class rectification circuits, and overcome the shortcoming that their exist, found the basic rectification circuit of single phase power supply poly phase rectification? this is the great new problem of rectification circuit and controlled rectification circuit basic research, and splitting commutating phase (comprising controlled rectification) circuit is exactly an invention of founding this basic research theory.
The object of the present invention is to provide a kind of direct current output ripple is little, ripple frequency is high, ripple simple single phase poaer supply in Lu is powered rectification and controlled rectification circuit.
The rectification circuit of the single phase poaer supply power supply that further object of the present invention provides and a kind ofly exchanges that input current abnormality is few, power factor and rectification efficiency are high.
The invention provides and a kind ofly split commutating phase and controlled rectification circuit what single phase alternating current power supply (comprise exchange controllable voltage regulating power supply) was transformed into the direct current supply load, it is characterized in that being connected with one with single-phase heterogeneous splitting phase circuit or the device of splitting between single phase alternating current power supply input and poly phase rectification comprise the input of controlled rectification, it comprises:
A splitting phase circuit that single phase poaer supply is split into polyphase source of forming by electric capacity, resistance, inductance and transformer, can use in the splitting phase circuit above-mentioned four kinds of elements and parts any two or more, perhaps whole.
A plurality of rectifications and controlled rectification device, they are connected single-phase splitting on the heterogeneous power supply with poly phase rectification or controlled rectification mode and form poly phase rectification, and its output direct current two ends can directly connect load or Lu ripple device and load, and load can be all kinds.
An input at single phase poaer supply connects an electric capacity and an inductance respectively, connecting load resistance between the other end of power supply and electric capacity flows through with regard to having the load current that is ahead of supply voltage, just have the load current circulation that lags in supply voltage and connect load resistance between the other end of power supply and inductance, therefore, an input at single phase poaer supply is serially connected with electric capacity and inductance respectively, at the other end of electric capacity and inductance respectively and when connecting load between the other end of single phase poaer supply, single phase poaer supply will split into the two-phase power supply.With three other ends of power supply, electric capacity and inductance, connect six rectifications or the controlled rectification device that are connected in the three-phase bridge rectification mode respectively, connect DC load at its output two ends, promptly become the Paraphase rectifying circuit that single-phase apportion becomes two-phase.It can obtain to double than single-phase bridge rectification ripple frequency on DC load, the direct voltage of pulsating voltage much less, if when big electric capacity Lu ripple is arranged on DC load, its current waveform distortion in the AC power input circuit is just much smaller than existing single phase rectifier circuit, and its power factor is also far above existing single phase rectifier circuit.Electric capacity and inductance are in series, and receive on the single phase poaer supply, also can split into polyphase source between the points of common connection of single phase poaer supply two ends and electric capacity and inductance.Just single phase poaer supply can be split into the polyphase source of more heterogeneous number in a word with the multiple combinational circuit of electric capacity, resistance, inductance and transformer, it is realized that the rectification of more heterogeneous number just can obtain direct current output more stably and higher ripple frequency.
Split the phase controlled rectification circuit and should comprise that also the single phase poaer supply input carries out the Paraphase rectifying circuit of AC voltage adjusting earlier.
It will be appreciated that from front summary, the invention provides a kind ofly that realize exchange conversion is become the Paraphase rectifying circuit of direct current with two-phase or the above poly phase rectification of two-phase, it also comprises splits the phase controlled rectification circuit with the single phase poaer supply power supply.
