Abstract

The invention is applicable to the technical field of power electronics, and provides a driving circuit and a driver. The driving circuit comprises a driving unit and a full bridge rectifying unit, wherein the driving unit is externally connected with a signal generator, and is connected with the full bridge rectifying unit; the full bridge rectifying unit is suitable for being connected with a load; the driving unit receives occurrence signals from the signal generator, generates a first different-mode signal and a second different-mode signal by using the occurrence signal, and inputs the first different-mode signal and the second different-mode signal into the full bridge rectifying unit; the whole bridge rectifying unit rectifies the received first different-mode signal and second different-mode signal to generate a differential signal; and the differential signal is used for driving the load. The driving circuit provided by the invention can be used for generating the differentialsignal with strong anti-interference capability, so that the ground network test accuracy is improved.

Description

technical field [0001] The present application relates to the technical field of power electronics, in particular to a driving circuit and a driver. Background technique [0002] The ground grid is a lightning discharge network composed of ground leads and several ground bodies. In the field of modern lightning protection technology, the ground grid is a key link related to the success of lightning protection. Therefore, after the ground grid is built, it is necessary to test the ground grid. [0003] In the ground network test, it is necessary to send a test signal to the ground network, and the test signal provides a measurement basis for the receiving device. However, in the prior art, the anti-interference ability of the test signal sent to the ground network is poor, resulting in inaccurate test results. Contents of the invention [0004] In view of this, the embodiment of the present application provides a driving circuit and a driver to solve the problem in the pr...
