Description
Technical field
The utility model relates to rectification field, particularly relates to a kind of half-wave rectifying circuit.
Background technology
Rectification circuit can utilize the rectifying device (as rectifier diode, thyristor) with unilateral conduction the sinusoidal ac that size, direction all change to be transformed into the direct current of unidirectional pulsation, when input power is industrial frequency AC 220V, through voltage regulator pressure regulation, obtain the alternating voltage that amplitude is adjustable, adjustable range 0-220V, then through rectification circuit direct voltage.The utility model proposes a kind of half-wave rectifying circuit, the rectification of high-quality can be carried out the alternating current of input.
Utility model content
In view of this, the utility model provides a kind of half-wave rectifying circuit, comprise the first inductance L 1, second inductance L 2, diode VD, resistance RL, wherein, described first inductance L 1 and the second inductance L 2 form inductance pair, and one end of the second inductance L 2 connects the input of diode VD, the output contact resistance RL of diode VD, the other end of resistance RL connects the other end of the second inductance L 2.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment below, apparently, accompanying drawing in the following describes is embodiments more of the present utility model, for those of ordinary skills, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
The structural representation of the half-wave rectifying circuit that Fig. 1 provides for the utility model one embodiment.
Embodiment
For making the object of the utility model embodiment, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in the utility model embodiment, clear, complete description is carried out to the technical scheme in the utility model embodiment, obviously, described embodiment is the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, the every other embodiment that those of ordinary skill in the art obtain under the prerequisite not making creative work, all belongs to the scope of the utility model protection.
The structural representation of the half-wave rectifying circuit that Fig. 1 provides for the utility model one embodiment, as shown in Figure 1, the half-wave rectifying circuit of the present embodiment, comprises the first inductance L 1, second inductance L 2, diode VD, resistance RL, wherein, described first inductance L 1 and the second inductance L 2 form inductance pair, one end of second inductance L 2 connects the input of diode VD, and the output contact resistance RL of diode VD, the other end of resistance RL connects the other end of the second inductance L 2.
The course of work of circuit is: at the positive half cycle of U2, namely go up just lower negative time, rectifier diode VD adds forward voltage and conducting, if ignore the voltage drop of rectifier diode own, then output voltage Uo=U2.At the negative half period of U2, under namely upper negative just, rectifier diode VD ends by reverse voltage, no current, therefore Uo=0V in rectifier diode and load RL.Circuit working waveform as shown in Figure 1.
In circuit, rectifier diode is selected according to average current and inverse peak voltage.The electric current flowing through rectifier diode in half-wave rectifying circuit is equal with output current.
The inverse peak voltage that the inverse peak voltage of rectifier diode can bear when referring to its not conducting, selects Guan Shiying to select the pipe that this value of resistance to pressure ratio is high, in order to avoid pipe is breakdown.
Last it is noted that above embodiment is only in order to illustrate the technical solution of the utility model, be not intended to limit; Although be described in detail the utility model with reference to previous embodiment, those of ordinary skill in the art is to be understood that: it still can be modified to the technical scheme described in foregoing embodiments, or equivalent replacement is carried out to wherein portion of techniques feature, and these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of each embodiment technical scheme of the utility model.
