15kHz 4200W Automatic Digital Ultrasonic Welding Machine Generator For Plastics PVC Car Parts Meter Welding Machine

The driving power generator of ultrasonic plastic welding equipment is a real-time software frequency tracking algorithm for Ultrasonic welding transducers. It only needs to get the fundamental frequency component of the signal through a low-pass filter, and then carry out simple mathematical operations on the fundamental frequency component to achieve real-time frequency tracking. Compared with the previous methods, this method has less calculation amount for ultrasonic transducers, faster tracking speed, and higher accuracy
