| Abstract: | In order to raise the power of the ultrasonic welding machine and improve its character, Insulating Grid Bipolar Transistor(IGBT) tube is used as power element in designing the hardware system of power generator of ultrasonic welding machine in this paper.Algorithm about SPWM sequence is realized by means of the rule sampling. The software system is drawn up, the controlling of the algorithm about SPWM sequence is realized in 8098 MCS, and automatic tracing of frequency is fulfilled. The result indicates that the system has high controlling quality and high precision in controlling frequency. The developed generator can be used in ultrasonic plastic welding machine. |
