Abstract
The invention discloses a voltage-doubling rectifying linear direct-current power supply which comprises a rectifying diode and a filtering current-limiting capacitor connected with the rectifying diode.
Description
Technical field
The invention discloses a kind of voltage multiplying rectifier linear DC power supply, belong to technical field of electronic products, especially relevant with transformerless DC power supply.
Background technology
DC power supply is applied in a lot of fields.Known DC power supply comprises transformer, rectification circuit, filter circuit, control circuit etc.The defective one of this known DC power supply is that used parts are many, the cost height; The 2nd, need to use the transformer transformation, transformer self has certain loss, wastes energy.
Summary of the invention
The objective of the invention is to disclose a kind of voltage multiplying rectifier linear DC power supply, this voltage multiplying rectifier linear DC power supply does not need transformer, and used parts are few, and cost is low, and energy consumption is low, dependable performance.
Taked following technical scheme for realizing purpose of the present invention:
Make a kind of voltage multiplying rectifier linear DC power supply, the filtering current limiting capacitance that this voltage multiplying rectifier linear DC power supply comprises rectifier diode, links to each other with rectifier diode is made voltage multiplying rectifier linear DC power supply.
Characteristics of the present invention be simple in structure, easy to manufacture, cost is low, be easy to promote; Its remarkable advantage is a transless, and used parts are few, and cost is low, and energy consumption is low, dependable performance.
Further describe technical characterictic of the present invention below in conjunction with accompanying drawing:
Accompanying drawing: the structural representation of one embodiment of the invention.
Among the figure: D
1, rectifier diode C
1, filtering current limiting capacitance D
2, rectifier diode
C
2, the filtering current limiting capacitance
Embodiment
As shown in drawings, the D among the figure
1And D
2Be rectifier diode, C
1And C
2Be the filtering current limiting capacitance, rectifier diode D
1And D
2After the alternating current arrangement, through filtering current limiting capacitance C
1And C
2Filtering, the output DC source.
The present invention has the buck effect.One, boost: as shown in drawings, rectifier diode D
1With filtering current limiting capacitance C
1Form half-wave rectifying circuit, output voltage is
Rectifier diode D
2With filtering current limliting C
2Output voltage also be
Therefore output voltage is both stacks, and maximum output voltage is
The present invention can expand to n level circuit, then can obtain n doubly
Voltage.Two, step-down: a little less than this circuit carrying load ability, when load was zero load, voltage output was maximum, and when having load, along with the load current increasing of load, the output voltage approximately linear descends, and finally is output as zero.
Embodiment 1
When input voltage is alternating current 220V, capacitor C
1And C
2Select 10uf for use, then output voltage changes as follows:
The present invention selects the filtering current limiting capacitance C of different capabilities
1And C
2, can obtain different output currents, for example the electric capacity of Xuan Zeing is C
1And C
2N doubly, then can obtain n output current doubly; The opposite electric capacity of selecting is more little, and then output current is more little.
