Abstract

The invention provides a bipolar pulse signal generating device. The bipolar pulse signal generating device comprises a unipolar pulse output unit which is used for outputting a unipolar pulse signal; and a piezoelectric ceramic transformer which comprises an input end, an output end and a piezoelectric body, wherein the input end is connected with the unipolar pulse output unit and is used for receiving the unipolar pulse signal; the piezoelectric body is used for converting the unipolar pulse signal into a bipolar pulse signal; and the output end is used for outputting the bipolar pulse signal.

Description

technical field [0001] The invention relates to the field of electrical signal processing, in particular to a bipolar pulse signal generating device. Background technique [0002] The bipolar pulse signal has many uses, and the existing solution is to generate the bipolar pulse signal through a push-pull switch circuit. figure 1 shows a push-pull switching circuit, as figure 1 The circuit shown includes a driving circuit L1, a driving circuit L2, a switching tube Q1, a switching tube Q2, a capacitor C1, a capacitor C2, a diode D1, a diode D2, positive and negative power supplies. In this circuit, L1 and L2 alternately output the drive current, so that Q1 and Q2 alternately connect the positive and negative power supplies in turn, thereby providing bipolar pulse signals to the load. [0003] The problem of the prior art is that the structure of the bipolar pulse signal generating circuit is relatively complicated, and the parameters of devices such as switching tubes in the...
