Embodiment

[0031] An embodiment of the present invention provides a driving device, which is applied to, for example, figure 1 As shown, it includes: a control terminal 1, a pulse generator 2, a drive circuit 3 and an isolated power supply 4.

[0032] The control terminal 1 of the embodiment of the present invention is used to generate a corresponding pulse generation signal according to the low-level pulse width, high-level pulse width, pulse type, and pulse trigger time input by the user.

[0033] Specifically, the user can select the type of output pulse signal through the control terminal 1, such as: single double pulse signal, single single pulse signal, periodic repetition double pulse signal and periodic repetition single pulse signal. In addition, the user can set the low Level pulse width, high level pulse width, pulse type, pulse trigger time to get the required pulse signal. Control the terminal 1 and the above information to obtain the corresponding pulse generation signal, ...

Abstract

The invention discloses a driving device which comprises a control terminal, a pulse generator, a driving circuit and an isolation power supply, wherein the control terminal generates a corresponding pulse generation signal according to pulse information input by a user; the pulse generator is connected with the control terminal in a wireless communication mode, switches to a corresponding working mode according to the pulse generation signal, and generates a pulse signal of a corresponding pulse type; the driving circuit performs level conversion on the pulse signal to obtain a driving signal; and the isolation power supply realizes strong and weak current isolation among an external power supply, the pulse generator and the driving circuit, and supplies power to the pulse generator and the driving circuit. According to the invention, the user sends pulse information to the pulse generator in a wireless communication mode through the control terminal, the pulse generator is switched to a corresponding working mode according to the pulse information to generate a corresponding pulse signal, and the driving circuit performs level conversion on the pulse signal to obtain a driving signal, so that a required pulse signal can be obtained without modifying and programming a built-in program of the pulse generator, the experiment period is short, and the operation is convenient and safe.

Description

technical field [0001] The invention relates to the technical field of power electronics, in particular to a driving device. Background technique [0002] The basic task of the drive device is to convert the signal from the information electronic circuit into a signal that is added between the control terminal and the common terminal of the power electronic device to turn it on or off according to the requirements of its control target. For semi-controlled devices, only the turn-on control signal is required, while for full-control devices, both turn-on control signals and turn-off control signals are required to ensure that the devices are reliably turned on or off as required. At present, there are three main ways to obtain control signals: one is obtained by using a signal generator; the other is obtained by programming a programmable controller such as DSP; the other is realized by a circuit built with basic digital circuit hardware such as a 555 timer. . However, the ...
