基于FPGA的超声波焊接电源频率跟踪研究
Research on Frequency Tracking of Ultrasonic Welding Power Supply Based on FPGA
摘要
Abstract
The frequency trackingspeed and accuracy of ultrasonic welding power supplies directly affects the quality of welding. For slow of tracking, load mutation volatile lock and other shortcomings of the analog PLL, we develop a kind of ultrasonic welding power source based on FPGA.This study focuses on the design of the power control system, and a simulation software is to verify modules. The ultrasonic welding test platform is set up to record relevant test data and analyze the data.关键词
