Fig. 1 is a circuit diagram of the present utility model.
Embodiment
As shown in Figure 1, the utility model is a kind of power supply and control integrated apparatus, comprising: capacitance resistance reduction voltage circuit 1, rectification circuit 2, control chip 3 and relay 4 that order is electrically connected; Above-mentioned each assembly is installed on the same circuit board.
Wherein, capacitance resistance reduction voltage circuit 1 is made up of the resistance R 1 and the capacitor C 1 of series connection; Rectification circuit 2 comprises by diode Z1, Z2, Z3, Z4 forms bridge rectifier circuit, its ac input end is connected with two power leads respectively, be connected with capacitance resistance reduction voltage circuit 1 between one of them ac input end and the power supply, be connected with fuse 11 between another ac input end and the power supply.Preferably, be connected in parallel to voltage stabilizing diode Z5 and filter capacitor C2 between the direct current output cathode of bridge rectifier circuit and the negative pole.Rectification circuit 2 is electrically connected with chip 3 and relay 4 respectively, to both power supplies.Control chip 3 is connected with more than one sensor 9 (difference according to detected parameters is provided with), sensor 9 exports sensed parameter to control chip 3, control chip 3 is connected with the solenoid of relay 4, pass to control chip 3 according to the sensed parameter output signal, by the contact switch break-make of control chip 3 pilot relays 4.Relay 4 output terminals connect heat-generating disc 10.Control chip 3 is connected with some function keys 7 (depending on actual functional capability to need the number of set-up function key), and the user selects the different working modes of control chip 3 by pressing function key 7.Control chip 3 also can be connected with loudspeaker/hummer (not illustrating in the drawings), can send button sound, EOP (end of program) prompt tone etc. as required.Relay 4 and hummer are provided with signal amplification circuit element (not illustrating in the drawings), and the signal of control chip 3 outputs is delivered to relay 4 and loudspeaker/hummer after amplifying by the signal amplification circuit element again.
Principle of work: step-down is mainly finished by resistance R 1, capacitor C 1, the size of the height of voltage and amount of capacity decision resistance R 1 and capacitor C 1.With the ac input end of AC power N utmost point serial resistance R1 successively, capacitor C 1, commutation diode Z1, Z3 polyphone, an end of the AC power L utmost point is connected to another ac input end of commutation diode Z2, Z4 polyphone by fuse 11.To parallel connection, and the negative pole of Z3 and two commutation diodes of Z4 forms a bridge rectifier circuit to parallel connection as the positive pole of Z1 in Fig. 1 circuit and two commutation diodes of Z2.During energized, the just very galvanic positive voltage that is in parallel, the negative pole that is in parallel is galvanic negative voltage, at anodal and voltage stabilizing diode Z5 of negative pole two ends parallel connection with the direct current voltage stabilizing, electrochemical capacitor C2 in parallel again carries out filtering with direct supply, make entire circuit form step-down, rectification, voltage stabilizing, filtering circuit, D.C. regulated power supply is transported to control system (being control chip 3) and relay 4.Control chip 3 stores multiple function program, is transported to control chip 3 through the triggering command of function key 7, transmits temperature signals through sensor 9.By the switching of the temperature and time control program pilot relay 4 of control chip 3, restriction is to the delivery of heat-generating disc 10, thereby arrives the dual purpose of temperature and time control.Owing to utilized resistance, capacitance decompression, and transferred alternating current to direct current to control chip and relay power supply, therefore realized power supply and the control panel that is controlled to be one through overcommutation.
