WELDING-TYPE POWER SUPPLY SYSTEMS AND METHOD OF DETERMINING INDUCTANCE OF A WELDING-TYPE CABLE FOR INDUCTANCE COMPENSATION

摘要

Systems and methods for inductance compensation in a welding- type system (100) include a reel (102) configured to wind a welding- type cable (106, 106') to reduce a first portion of the welding-type cable (106, 106', 108) extending from the reel (102), and to unwind to increase the first portion of the welding-type cable (106, 106') extending from the reel (102), wherein a second portion (108) of the welding-type cable is at least partially wound around the reel (102) when stored. A controller (110) determines a first length of the first portion (106, 106') of the welding-type cable, calculates a first inductance of the first portion (106, 106') of welding-type cable extending from the reel (102) based on the first length, determines a second length of the second portion (108) of the welding-type cable, calculates a second inductance of the second portion (108) of welding-type cable wound around the reel (102) based on the second length, and calculates a cable inductance of the welding-type cable (106, 106', 108) based on the first inductance and the second inductance.
