中文摘要	A frequency and amplitude modulation (FM/AM) pulse generator with large amplitude and narrow width was introduced,by using it,the effect of electro-plasticity induced by current pulse could be applied to metal wire drawing. The conventional three-phase full - bridge rectifier and LC filter were adopted in its primary energy storage module. In its intermediate energy storage module, a buck converter was used, and the charging voltage of electric capacitance, which controlled the amplitude of output pulse current,was adjusted by a full -controlled power switch IGBT. The output current pulse with narrow width was formed through the electric - capacitance, parasitic inductance in the output loop and the equivalent load resistance when the high - frequency semicouductor controlled rectifier(SCR) was controlled to be turned on. The frequency and amplitude of output current pulse could be adjusted in real time and displayed digitally. The experimental results show that the power supply system operates stably, and the frequency and amplitude of its output current pulse can be adjusted conveniently and controlled precisely.
