The principle of adjusting duty ratio and frequency of PWM wave was researched,and the principle of power amplifier drive circuit which can provide enough power and current was analyzed. The corresponding circuit was made and tested. The theoretical analysis and test results show that the circuit structure used in moving coil electrical-mechanical transformer is simple and effective,and can achieve the predetermined requirements.
