On TIG-MIG hybrid welding process (TIG: DCEN and MIG: DCEP), the stability of MIG arc
can be kept even in pure inert shielding gas by the effect of hybridization with TIG arc, and it …

This paper deals with a middle-frequency resistance spot welding system. It consists of an
input converter, welding transformer, and a full-wave rectifier mounted at the transformer …

This paper presents a circuit structure with a novel inverter that is applicable to arc welding
machines. The output rectifier configuration adopts the current doubler rectifier with two …

This study presents the analysis and design of a novel technique that improves the efficiency
of the conventional forward DC–DC converter by reducing switching losses, along with a …

Several power decoupling techniques have been studied in the specialized literature to
reduce or eliminate the ripple at 120 Hz intrinsic to the nature of single-phase AC-DC …

This paper deals with a middle frequency resistance spot welding system. It consists of a
semiconductor input converter, a single phase welding transformer with one primary coil and …

This study presents a new circuit topology of the active edge resonant snubber-assisted half-
bridge soft-switching PWM inverter-type DC–DC high-power converter for DC bus feeding …

This paper presents a new circuit topology of dc busline switch-assisted full-bridge soft-
switching PWM inverter type dc-dc power converter which is composed of typical voltage …

Conventional welding machines that are available in the market, runs by Grid power (AC)
are bulky in size and are not cost-effective. Those existing systems have the problem of low …
