In ultrasonic application, in many occasions, positive and negative symmetrical electric pulses are needed to excite a probe to generate positive and negative symmetrical sound waves, so that in-phase sound waves and anti-phase sound waves are mutually offset, and the required tissue imaging is realized; the positive and negative symmetry of the amplitude of the power supply voltage determines the positive and negative symmetry of the excitation pulse, and the amplitude error of the positive and negative electric pulses can cause the asymmetry of the transmitted sound waves, thereby influencing the imaging quality.
In the traditional solution, positive and negative output voltages with symmetrical amplitudes are generated through a transformer; however, in practical use, since the transformer is subject to a manufacturing process, the symmetry error of the winding is large, and thus, positive and negative voltage values which are accurately aligned cannot be output.
