The application circuit of the electrical switch that Fig. 3 provides for the present invention.
Detailed description of the invention
For making the present invention become apparent, hereby with preferred embodiment, and accompanying drawing is coordinated to be described in detail below.
As it is shown in figure 1, the high-pressure electronic switch internal of a kind of frequency of present invention offer and variable-width has following functions
Module: power module, input control signal process circuit, open the drive circuit of switch, disconnect the drive circuit of switch, high pressure
Switch module.Hereinafter modules is explained respectively.
Power module, the control circuit of the electrical switch that the present invention provides uses direct current 5V to power, within electrical switch
Drive circuit then uses the DC-voltage supply of 30V and 350V, therefore power module need to be converted into direct current 5V 30V and
350V, so comprising oscillating circuit, power tube, transformator, PWM circuit etc. in power module.
As in figure 2 it is shown, input control signal processes the input warp that circuit includes NAND gate one U1, NAND gate one U1
By resistance R1 connection control signal Vi, another input of NAND gate one U1 is via resistance R2 ground connection, and NAND gate one U1's is defeated
Going out two inputs that end connects NAND gate two U2, the outfan of NAND gate two U2 is via electric capacity C1 and resistance R3 ground connection, with non-
Two inputs of door three U3 access between electric capacity C1 and resistance R3, and the outfan of NAND gate three U3 connects the two of NAND gate four U4
Individual input, the outfan of NAND gate four U4 is formed and drives signal Vo
Control signal Vi brought from single-chip microcomputer or other kinds of controller first pass around Schmidt imported with
Not gate one U1 and NAND gate two U2 is filtered shaping, filtering interference signals.Then the control signal of switch is carried out width
Adjust, by resistance R3 and the discharge and recharge of electric capacity C1, by the time constant of RC circuit and NAND gate three U3, NAND gate four U4
The input threshold magnitude of voltage of schmidt trigger type, limits the width controlling pulse, to ensure that control signal has enough arteries and veins
Rush width and deliver to drive circuit, and carry out the opening time of limit switch by limiting the width controlling pulse.Because excessive opens
The time of opening can cause the increase of high-voltage MOSFET pipe power consumption, damages beyond the peak power of pipe permission.Pass through control signal
Process circuit and switch driving circuit, realize the regulation of switching frequency and switching width.
High voltage switching module, owing to the single drain electrode of MOSFET pipe and the running voltage of source electrode are extremely difficult to several kilovolts, just
It is that to reach price be also the most expensive.The high voltage switching module of the present invention realizes senior engineer by the series connection of high-voltage MOSFET pipe
Make the requirement of voltage.Then in order to realize the ability of logical big electric current, MOSFET pipe being carried out parallel combination again, finally this height presses off
Close module and be capable of the purpose of high pressure big electric current.
Switch open drive circuit, is coupled to high-voltage MOSFET pipe group by transformer-coupled mode by opening signal
Grid, is provided with accumulator at grid, for maintaining the constant conduction of MOSFET.
Switch off drive circuit, same use transformer-coupled mode, when activated between arrived the intended time, open
Move and switch off drive circuit, the energy of MOSFET tube grid is discharged rapidly, reach to disconnect the purpose of switch.
As it is shown on figure 3, the application drawing of a kind of high-pressure electronic switch provided for the present invention, the switch of the present invention has 7
Control pin, wherein: 1 foot, for triggering signal input, needs during application to access resistance to earth, such as 100 ohm；2 feet are power supply ground
