Adopt the beneficial effect of technique scheme: easy-to-connect, visual in image, solve Power Electronic Technique desk lamp with dimmer switch application on skill training and examination, rectification, the knowledge apply of AC voltage adjusting aspect and comparative analysis can be strengthened, be closely connected real daily life, the ability of improve " studying in order to practise ", drawing inferences about other cases from one instance.
Accompanying drawing explanation
Fig. 1 is desk lamp with dimmer switch circuit diagram of the present invention.
Embodiment
The present invention is specifically introduced as follows below in conjunction with drawings and Examples:
A kind of novel desk lamp with dimmer switch actual training device, have bracing frame, bracing frame is placed with circuit board, circuit board is provided with 3 kinds of desk lamp with dimmer switch circuit.Single phase ac regulation circuit 1, single phase ac regulation circuit 2 and single phase full bridge semi controlled rectifier, operating switch and knob, incandescent lamp, described circuit board each several part is connected with wire according to electric wiring.
Described desk lamp with dimmer switch circuit for load, reaches illumination object with 3 kinds of technical schemes with the incandescent lamp used in real life, i.e. single phase ac regulation circuit 1, single phase ac regulation circuit 2 and single phase full bridge semi controlled rectifier.Single phase ac regulation circuit 1 and the difference of single phase ac regulation circuit 2 are that the principle of trigger circuit is different.Desk lamp with dimmer switch circuit diagram as shown in Figure 1, specifically:
Single phase ac regulation circuit 1, be power converter device with bidirectional thyristor, and utilize the feature of RC charge-discharge circuit and bidirectional trigger diode, in every half cycle, by carrying out phase-shifting trigger control to the break-make of bidirectional triode thyristor, can the effective value of regulation output voltage easily.Namely by the RP1 knob on regulating circuit plate, the bright-dark degree of incandescent lamp can be regulated.
Single phase ac regulation circuit 2, circuit is made up of trigger circuit, controlled device (bidirectional thyristor) and load (bulb).Discharge and recharge is constantly carried out through unijunction transistor BT33 and pulse transformer in RC loop, and regulator potentiometer RP1 can change the cycle of discharge and recharge, and consequent spike train is added to the gate pole of bidirectional thyristor, achieves the Regulation Control to output load.Namely by the RP2 knob on regulating circuit plate, the bright-dark degree of incandescent lamp can be regulated.
Single phase full bridge semi controlled rectifier, utilize 2 thyristors and 2 diode composition brachium pontis, 2 thyristors are under the control of trigger pulse, and conducting in turn, becomes direct current by 220V AC rectification, and supply incandescent lamp is practical.Circuit adopts typical single-junction transistor trigger circuit, first by synchrotrans step-down, the primary coil of synchrotrans is connected on 220V alternating current input power supplying, secondary coil obtains the alternating voltage of same frequency, through single-phase bridge rectification, become pulsating dc voltage, then become trapezoidal wave voltage through stabilivolt slicing.This voltage is the operating voltage of unijunction transistor trigger circuit.By the RP3 knob on regulating circuit plate, namely implement different phase-shifting trigger and control, the bright-dark degree of incandescent lamp can be regulated.
In addition, instrument connection is provided with in circuit, test voltage wave is respectively: 220V AC-input voltage, incandescent lamp loads voltage, bidirectional thyristor voltage, bidirectional thyristor trigger voltage, bridge-type uncontrollable rectifier output voltage, stabilivolt voltage, unijunction transistor emitter voltage, unijunction transistor base voltage, thyristor AK both end voltage, is convenient to waveform testing, fault analysis and investigation.
Power switch: the energising and the power-off that control whole system.After power switch is connected, circuit normally works.Now can adjustment operation knob RP1, RP2 or RP3, test voltage wave, carries out skill training or examination.
