Abstract
A kind of three-tube type full-wave rectifier, it is by step-down electric capacity C1, positive and negative halfwave rectifier diode D1, D2, and negative half-wave energy accumulation power consumption sense L and its accumulation of energy export uses diode D3, dividing potential drop---and filtering electrochemical capacitor C2, voltage-stabiliser tube VS and load RL are formed.It replaces four pipe rectifier bridges to achieve full-wave rectification with three diodes and an inductance, decreases energy consumption and the volume of rectifier.
Description
Technical field:
The design's three-tube type full-wave rectifier belongs to AC rectification power supply electrical equipment.
Technical background:
In rectification power circuit, we know, by AC-DC under single-phase transless condition, obtain the electric current bridge rectifier of full waveform, bridge rectifier four diodes, during rectification, the positive and negative half-wave current of alternating current all will flow through two rectifier diodes, rectification energy consumption is large, diode heating fin dispels the heat, and fin volume is large, and therefore not only energy consumption large volume is not little yet for rectifier.Can under the condition reducing diode, accomplish both to decrease energy consumption and volume, accomplish that again full-wave rectification exports, this is the object that we pursue.
Summary of the invention:
The order of the design is to provide a kind of under diode is less than four conditions, accomplishes not only to reduce energy consumption and volume but also can the full-wave rectifying circuit electrical equipment that exports of all-wave.
For achieving the above object, a kind of three-tube type full-wave rectifier that the design provides, its circuit is called for short electric capacity C1 by step-down electric capacity C1[], positive and negative halfwave rectifier diode D1, D2[are called for short diode D1, D2], negative half-wave energy accumulation power consumption sense L[is called for short inductance L] and its accumulation of energy output diode D3[abbreviation diode D3], dividing potential drop---filtering electrochemical capacitor C2[is called for short electric capacity C2], voltage-stabiliser tube VS and load RL is formed.One end of the one termination civil power of electric capacity C1., the positive pole of another terminating diode D1 and the negative pole of diode D2; The positive pole of diode D2 with D3 is connected inductance L; The negative pole of diode D1, D3 and the positive pole of electric capacity C2 are connected with the negative pole end of voltage-stabiliser tube VS becomes power output end, i.e. positive pole; And the other end of inductance L, electric capacity C2, voltage-stabiliser tube VS three is held with connecting with the other end [zero line] of civil power with forming power supply, i.e. negative pole; Load RL is connected between the both positive and negative polarity of power supply..Again, electric capacity C1 is 1-3 μ F capacity, the high-voltage capacitance that more than 400V is withstand voltage; Electric capacity C2 is Large Copacity { 20 μ F-470 μ F.} low withstand voltage (> 16V-63V) small size electrochemical capacitor; The voltage stabilizing value of voltage-stabiliser tube VS and the inductance value apparent load of inductance L require and determine; Load RL is resistive or inductive even load.
During this circuit working, civil power---220V alternating current is by after electric capacity C1 step-down, its positive half wave transfers to load RL through diode D1 rectification, bear half-wave through inductance L, diode D2 and electric capacity C1 because of self-induction accumulation of energy in inductance L, this accumulation of energy transfers to load RL through diode D3 again, and civil power is defeated by before load also through electric capacity C2 dividing potential drop, filtering and voltage-stabiliser tube VS voltage stabilizing.
This circuit three diodes achieve the full-wave rectification of rectifier, namely which reduce its diode number, energy consumption and volume.
Accompanying drawing illustrates:
Fig. 1 is the design's three-tube type full-wave rectifier circuit schematic diagram.
Embodiment:
As shown in the figure, a kind of three-tube type full-wave rectifier, it is by electric capacity C1. (1 μ F400V), diode D1, D2, D3{1N4007}, inductance L (5mH), and electric capacity C 2{470 μ F/16V}, voltage-stabiliser tube VS{5V} and load are formed.
The design is practical, imitates.
