Accompanying drawing explanation
Fig. 1 is the schematic diagram of electric cooker relay drive circuit described in the utility model.
Embodiment
The technological means realized for making the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with embodiment, setting forth the utility model further.
See Fig. 1, a kind of electric cooker relay drive circuit described in the utility model, comprise power supply VCC, described power supply VCC is connected with the emitter of triode Q1, the base stage of triode Q1 is connected with resistance R1, the other end of described resistance R1 is provided with output P_OUT1, the collector electrode of triode Q1 is connected with diode D1, described diode D1 is in parallel with relay K 1, the collector electrode of the other end connecting triode Q2 of diode D1, the grounded emitter of triode Q2, triode Q2 base stage is connected with resistance R3, the other end of resistance R3 is parallel with resistance R5 and electric capacity C2, the other end ground connection of described resistance R5 and electric capacity C2, described resistance R3 is also connected with diode D2, the other end of diode D2 is connected with electric capacity C1 and diode D3, the other end ground connection of diode D3, the other end contact resistance R2 and resistance R4 respectively of described electric capacity C1, the other end ground connection of described resistance R4, the other end of resistance R2 is provided with output P_OUT2.
Drive principle of the present utility model is as follows:
P_OUT1 output low level, P_OUT2 provides a square wave, relay K 1 conducting.
If one in these two conditions all can not meet this condition, then all can not conducting.
Detailed process is analyzed: if will make relay K 1 conducting, then triode Q1 and triode Q2 needs conducting.First the condition of triode Q1 conducting is made to be that P_OUT1 port is to a low level.Second step makes triode Q2 conducting, as can be seen from the figure, an electric capacity C1 is had in the drive circuit of triode Q2, and this electric capacity has been the effect every straight-through friendship, just can by electric capacity C1 by port P_OUT2 output waveform, thus make signal arrive the driving stage of triode Q2, electric capacity C2 time play filtering exactly, just become a stable level by complete for waveform.It can thus be appreciated that P_OUT2 mouth only has to a waveform, triode Q2 conducting just can be made.
More than show and describe general principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
