Abstract
PVC pipe is widely used in the fluid medium.In order to ensure the quality of the joining of pipes,the power supply for energysaving fusion welding machine is designed by using intelligent control technology and new power electronic devices.This power supply takes SCM as control core and uses fuzzy adaptive PID control technology to calculate the external environment temperature and the temperature of welding interface,and according to the voltage deviation,it uses fuzzy adaptive PID parameters to realize online self-correction and quickly find the appropriate duty cycle of output DC voltage and improves the welding speed.The πr type LG filter circuit and double DC HPWM converter circuit composed of IGBT are adopted for design of hardware circuit,which greatly improves the quality of output voltage.Finally,the designed power supply is simulated and analyzed.The result shows that the power supply saves the circuit cost,improves the rate of regulation and the stability of output voltage.关键词
