Embodiment 1

[0045] This embodiment describes a PVC gel small rapid activation circuit under the control of the pre-control circuit.

[0046] See Figure 5 When PVC gel is activated, only one pre-switch circuit is used. With the control of the PWM control signal, the frequency of the PWM control signal is 1 Hz. The front switch circuit can output a series of periodically stable PWM signals, and in the case of the next period, the PWM rising edge and At high levels, a charge excitation of PVC gel was completed, and the PVC gel was quickly activated at a number of cycle PWM rising edge and high levels.

[0047] The power of PVC gel activation is reduced to the original 1 / 10 ~ 1 / 6, which greatly reduces energy consumption, narrowing the volume of the power supply, and improves the circuit integration.

Embodiment 2

[0049] This embodiment describes a PVC gel small rapid activation circuit under the control of the rear switch circuit. See Image 6 When PVC gel is activated, only one rear switch circuit is used.

[0050] (1) The rear switching circuit can be set by the Timing of the PWM control module by the control signal of the PWM control module, and outputs a series of cycles less than 2T. 1 PWM signal, set the frequency of the PWM control signal to 5kHz, the signal guarantees it in less than T 1 During the time, current is unsaturated, the voltage does not reach the booster module gain voltage, that is, the supercharging module does not enter the protective self-locking state. In the cycle less than 2T 1 Under PWM signal excitation, PVC gel completed rapid activation.

[0051] (2) The current value of the PVC gel and the booster module can be reduced by introducing a series limit current resistor, which is less than the self-locking protection current of the boost module, and avoids there. ...

Embodiment 3

[0054] This embodiment describes a PVC gel small rapid activation circuit under the control of a front switching circuit and a rear switch circuit. See Figure 8 When PVC gel is quickly activated, a pre-switch circuit and a rear switch are used to combine control.

[0055] This embodiment combines two switching circuits, when the front switch circuit is operated, the rear circuit switch is closed, and the frequency of the PWM control signal is 1 Hz when the front switch is operating; the front switch circuit is closed. The frequency of the PWM control signal is 10 kHz when the rear switch is operated. The front switch circuit can control the control of the PWM control, the front switch circuit can output a series of periodically stable PWM signals, complete the rapid activation of the PVC gel; the rear switching circuit can be started with low currents The driving of the PVC gel is realized, that is, the effect of activating the driving two in one.

Abstract

The invention discloses an activation system for activating PVC gel, which adopts a switching circuit connected with a PWM control module, realizes conduction of high direct-current voltage provided by a pressurization module for the PVC gel by utilizing a switch of the switching circuit. The power supply is used for supplying power to the activation circuit, and the PWM control module works under the power supply of the power supply to generate a series of PWM control signals. The boosting module amplifies the voltage for high-voltage activation of the PVC gel; in addition, the switching circuit is influenced by the PWM control module to work; when the PWM control signal is at a high level, the switching circuit is closed and conducted, and when the PWM control signal is at a low level, the switching circuit is disconnected and not conducted. Thus, on-off of a PVC gel activation high-voltage circuit is realized, adjustability of current in different periods is ensured, power and energy loss of activation of PVC gel are reduced, activation time is shortened, activation efficiency is improved, and the requirement for activation power of the PVC gel is met; meanwhile, the WM control module, the pressurization module and the switching circuit are adopted, the integration level is high, and miniaturization is facilitated.
