Description

A kind of Electronic bicycle of solar energy charging pile switching circuit
Technical field
The utility model relates to a kind of switching circuits, and in particular to a kind of applied to Electronic bicycle of solar energy charging pile Switching circuit.
Background technique
Currently, using electromagnetic relay as opening in the switching circuit of common Electronic bicycle of solar energy charging pile mostly Element is closed, what electromagnetic relay was generally made of iron core, coil, armature, contact reed etc..As long as at coil both ends plus certain Voltage, will pass through certain electric current in coil, to generate galvanomagnetic-effect, armature will be under the action of electromagnetic attracting force The pulling force of return spring is overcome to be drawn to iron core, so that the movable contact with moving armature and stationary contact are attracted.After coil blackout, electromagnetism Suction also disappear therewith, armature will return to original position under the reaction force of spring, make movable contact and original quiet Contact release.It is attracted, discharges in this way, to achieve the purpose that conducting in circuit, cutting.Since electromagnetic relay works Always there is contact movement in the process, so influencing the working life of relay there are mechanical loss.And electromagnetic relay passes through touching Point is attracted, discharge reach point, conjunction electric current, reliability is lower.Furthermore the driving power consumption of electromagnetic relay is larger.
The switching circuit of another solar recharging stake is to manage (Metal-Oxide-Semiconductor using MOSFET Field-Effect Transistor Metal-Oxide Semiconductor field effect transistor) it is used as switch element to be connected on charging Circuit output negative side, but when MOSFET pipe disconnects, the output cathode of charging circuit is still charged.
Summary of the invention
In order to overcome existing electromagnetic relay as switch element, that there are power consumptions is big, reliability is low and working life is short Etc. technical problems, the utility model a kind of Electronic bicycle of solar energy charging pile switching circuit is provided.
A kind of Electronic bicycle of solar energy charging pile switching circuit provided by the utility model the technical solution adopted is that:
The switching circuit includes: P-channel MOSFET pipe Q1, NPN type triode Q2, two divider resistance R1, R2, and one A transistor base current-limiting resistance R3;
The connection relationship of the switching circuit is: base stage current-limiting resistance R3 mono- terminates control signal end A, three poles of another termination The base stage of pipe Q2, the emitter of triode Q2 connect power cathode, and collector connects one end of divider resistance R2, divider resistance R2's The other end meets the grid of MOSFET pipe Q1 and one end of divider resistance R1, another termination MOSFET pipe Q1 of divider resistance R1 simultaneously Source electrode and positive pole, the drain electrode of MOSFET pipe Q1 connects the anode of electric bicycle charging terminal;
The working principle of the switching circuit is: control signal end A accesses the control signal of high and low level, high level letter It number is exported by single-chip processor i/o mouth, voltage range 2-5V;Low level signal is also exported by single-chip processor i/o mouth, voltage 0.P ditch Gate source voltage when road MOSFET pipe Q1 is connected is generally 10-15V.When control signal end A is high level, NPN type triode Q2 is connected, and has electric current to flow through on two concatenated divider resistance R1 and R2, generates voltage drop, and partial pressure on divider resistance R1 is obtained Voltage be added between the grid and source electrode of P-channel MOSFET pipe Q1, and then control the conducting of MOSFET pipe Q1, power supply is logical at this time The MOSFET pipe Q1 for crossing conducting charges to electric bicycle.When control signal end A is low level, NPN type triode Q2 Shutdown, the loss of voltage between P-channel MOSFET pipe Q1 grid, source electrode, MOSFET pipe Q1 are no longer turned on, and charging pile is no longer right at this time Electric bicycle charging.By the on-off of MOSFET pipe, the purpose of electric bicycle charging on-off is realized.
The beneficial effects of the utility model are: controlling by the on-off to MOSFET pipe, electric bicycle charging is realized In the process without electric arc, switching with low power electricity.Compared with using electromagnetic relay to carry out switching electricity, there is high reliablity, drive Advantage low in energy consumption is moved, and is had the advantages of simple structure and easy realization.With on cathode plus compared with the scheme of MOSFET pipe, managed in MOSFET After disconnection, the output cathode of charging circuit is not charged, enhances the safety of switching circuit.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is the circuit diagram of the utility model, and the diode in parallel with MOSFET pipe Q1 is MOSFET pipe Q1 in figure Parasitic diode.
Specific embodiment
The utility model proposes a kind of Electronic bicycle of solar energy charging pile switching circuits, practical to this with reference to the accompanying drawing It is novel to be described further.
Fig. 1 is the circuit diagram of the utility model, as shown in Figure 1, the termination control letter of base stage current-limiting resistance R3 mono- of 5K Number end A, it is another termination NPN type triode Q2 base stage, the emitter of triode Q2 connect power cathode and electric bicycle charging Cathode is held, collector connects one end of the divider resistance R2 of 10K, and the other end of divider resistance R2 connects the grid of MOSFET pipe Q1 simultaneously One end of the divider resistance R1 of pole and 5K, the source electrode and positive pole of another termination P-channel MOSFET pipe Q1 of divider resistance R1, The drain electrode of MOSFET pipe Q2 connects electric bicycle charging end anode.Here the model s9013 for the NPN type triode selected, choosing The model PJA3401A of P-channel MOSFET pipe, conducting voltage range are 10-15V, and battery charging voltage is 36V.
It is high level in control signal end A, triode Q2 is connected at this time, carries out electric resistance partial pressure ,-the 12V that partial pressure is obtained Voltage is added between the grid and source electrode of P-channel MOSFET pipe Q1, and MOSFET pipe Q1 is connected at this time, and charging pile passes through conducting at this time MOSFET pipe Q1 charge to electric bicycle.Voltage in triode Q2 shutdown, between MOSFET pipe Q1 grid, source electrode It disappears, MOSFET pipe Q1 is no longer turned on, and charging pile no longer charges to electric bicycle at this time.
