摘要： PROBLEM TO BE SOLVED: To provide a power source of an electric arc welder in which the induction time of switches is long, the clamping circuits of two parallel primary circuits can be suitably turned on in a suitable time, and the balance of capacitors can be taken.
SOLUTION: In the power source of an electric arc welder containing an inverter (which comprises two primary circuits connected to parallel circuits across the DC buses of an input rectifier; wherein each primary circuit including a capacitor is parallel to each primary winding section) and switches (which applies voltage to each capacitor across the primary winding section, so that each primary circuit alternatively generates a voltage pulse on the primary winding section, and induces the voltage pulse to each secondary circuit having a secondary winding combined with the primary winding and also connected to an output circuit), a soft ferrite saturable reactor is used for at least one of the parallel circuits and output circuits, and the voltage pulse is delayed in each primary winding section.

摘要： A plasma device including a power source for creating an AC output signal with a matrix transformer between said power source and a series circuit comprising a first lead and a second lead. The matrix transformer including at least two modules with a first primary portion formed of first and second tubes connected at one end and a second primary portion formed of third and fourth tubes connected at one end, with said third and fourth tubes mounted in, and electrically isolated from, said first and second tubes, respectively, where said concentric tubes define generally parallel elongated passages through the module. A secondary winding is wrapped through the elongated passages of each module. There is a first series circuit from the power source to the matrix transformer for passing the first polarity of the AC output signal through the first primary sections of the modules, a second series circuit from the power source to the matrix transformer for passing the second polarity of the output signal through the second primary sections, a rectifier for each of the secondary windings of the modules and a third series circuit connecting the rectifiers in series with the first and second leads so a voltage of over about 500 volts is across these leads.
