摘要
Abstract
To meet the requirements of new welding process,it is necessary to design a single-power source multi-output constant-current welding power supply.Under this background,a novel converter with constant-current output was designed,which can output dual DC current or single AC current according to the requirements of different welding processes.The working principle for this converter was analyzed in detail,the small-signal models in DC and AC working modes were established respectively on the basis of considering the effect of load current changes on the circuit performance,and the output impedance from the two kinds of output was derived.In addition,the frequency-domain simulations verified the small-signal models,and the load transient response speed of the converter was analyzed.Finally,an experimental prototype was built,and the theoretical analysis was validated by experimental results.关键词
