Fig. 1 is a schematic circuit diagram of the present invention.
Detailed Description
The present invention is described in further detail below with reference to the attached drawing figures.
Referring to fig. 1, in the tank amplifier circuit, Rx1, Rx2 and Rx3 are 100K resistors; ry1, Ry2, Ry3, Rt1, Rt2 and Rt3 are 39K resistors; vcc is 24V power 5W; the RL is an energy-saving electromagnetic switch with position maintenance, and needs 24V +/-10% of voltage, 10W of power, 57.6 ohms of resistance, 0.37-0.42A of driving current and 0.2S of power supply when in action; since Vcc power is only 5W and current is only 0.21A, the load cannot be directly driven.
By using the energy storage amplifying circuit, Vcc is connected to the input end of the energy storage amplifying circuit, and the electromagnetic switch is connected to the load end of the energy storage amplifying circuit. When the capacitor is fully charged, the voltage of the voltage points is 24V, the voltage of V0 is equal to that of V1, when the capacitor is switched on and K0 or K1 is switched on, the capacitor is discharged, when the capacitor is just switched on and discharged, the voltage of the capacitor is 24V, the RL voltage V0 and the current are reduced along with the discharge of the capacitor, the voltage of V1(V1 ═(V2-V0) × Rx/(Rx + Rt) + V0)) is reduced, when the voltage difference between V2 and V1 reaches the volt-ampere characteristic 0.7V of the conduction of Q1, the PNP triode Q1 is conducted, and the C1 continuously supplies power to the load RL through Q1; when the voltage of V2 drops, the circuit will automatically connect the next energy-storage capacitor to discharge, and keep the driving ability; k0 and K1 are load-on control switches, respectively corresponding to the forward action and reverse action of RL switch, and can be controlled by a controller; d0, D1, D2 and D3 are diodes 10A10 which are in forward conduction and reverse cut-off; q1, Q2 and Q3 are PNP power triode 2SB772, the base of PNP silicon tube is conducted when the voltage is lower than the emission voltage by about 0.7V; c1, C2, and C3 are 50V energy storage capacitors C10000 μ F, and a single capacitor power supply time t is RC × ln (E/Vt) 57.6 × 10000 × ln (24/21.6) × 10-6 is 0.06s, so 4 energy storage capacitors are needed to implement the power supply time, and the power supply time can be adjusted by adjusting the number of the energy storage capacitors.
V0 ═ V2 ═ e (-t/RC) immediately after K0 or K1 are turned on
V2-V1 ═ V2- ((V2-V0) × (Rx + Rt) + V0) ═ V2-V0 (/ (Rx + Rt)) ═ V2 × (1-e (-t/RC)) (Rt/(Rx + Rt)), as time t increases, V2-V1 increases to 0.7V, the voltammetric characteristic of Q1 being on, Q1 is on, and C1 starts to discharge.
Selecting resistance parameters:
voltage of current-voltage characteristic/Q1 base driving current of Ry-Q1 conduction
Vcc (1-e (-t/RC)) (Rt/(Rx + Rt)) ═ Q1 conduction volt-ampere characteristic voltage (1)
Vcc (1-e (-t/RC)) (Rx/(Rx + Rt)) ═ available voltage difference (2)
Rx and Rt can be calculated according to the formulas (1) and (2).
When the double-circuit switch works, the double-circuit switch is firstly switched to the position A, the charging path is switched on, the power supply Vcc charges the energy storage capacitor C, and at the moment, the load is in a disconnected state;
when power is needed to be supplied, the two-way switch is firstly turned to the position B, the power supply circuit is switched on, the energy storage capacitor C supplies power to the load, and the power supply Vcc is in a disconnected state at the moment.
The working principle is as follows: when the voltage is normal, the K0 is powered on for charging; when the K0 acts, the energy storage capacitor supplies power to the load RL, the voltage of V0 drops, the voltage of V1 drops, and when the voltage difference between V2 and V1 reaches the volt-ampere characteristic of Q1 conduction, the C1 supplies power to the load RL through Q1; 3. when the power is supplied by the C1, the V2 is reduced to a certain value, the C2 is automatically switched in to supply power, and the power is supplied for each capacitor for the sum of the power supply time when the power is effectively supplied by the C3 and the C4.
The invention is applicable to: when the actuator is not active frequently and the originally planned power supply is not sufficient to power the actuator, such as when an RC power supply is used to power an electromagnetic relay, when a large current is required to power a valve, when a large current is required to power a motor lock, etc.
Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
