Abstract :
This paper based on a self-designed general circuit on ultrasonic emissive, studies high-voltage pulse, driver pulse, monostable trigger circuit, RC charging and discharging process and resonant matching circuit of transducer. It also puts forward an expression which could calculate the capacitance of the match capacitor in series, which can do great well to help selecting devices and improve design efficiency and emission efficiency. Finally, it does some experiments to test the expression, and it is reasonable and scientific.
