摘要：In a power source for an electric arc welder including an inverter having twoprimary circuits connected in a series circuit across the DC bus of an input rectifier whereeach primary circuit comprises a capacitor parallel with a primary winding section and a
switch to apply the voltage of the capacitor across the primary winding section, so thatthe primary circuits alternately create a voltage pulse in the primary winding sections toinduce voltage pulses in a secondary circuit having a secondary winding coupled to saidprimary windings and connected by an output circuit to an output welding circuit. There isprovided one improvement. The improvement is a soft ferrite saturable reactor in atleast one of the series circuit or the output circuit to delay the voltage pulse in theprimary winding sections.
