“…The secondary side AC-DC conversion stage consists of a current multiplier stage, derived from the current-doubler rectifier [9]. The welding process is modeled according the standard UNE-EN 60974-1 [12], which defines the conventional load voltage for a specific welding process.…”

“…3. The current multiplier is obtained from the parallel connection of two current doubler rectifiers [9]. The advantages of this configuration are enhanced with respect to the original current doubler rectifier and are related to lower conduction losses and simplification of the transformer, as each secondary deals with only quarter of Iw.…”

“…Operating at constant switching frequency, the total primary transformer current is modulated with the phase displacement between the input voltages to the resonant tanks, achieving zero voltage switching (ZVS) under all load conditions. The secondary rectifier section is designed with a current doubler structure [8][9], also unfolded in two stages connected in parallel at the output to reduce conduction losses. Therefore the transformer connection to the switching structures is series inputs parallel outputs.…”

Abstract-A new multiphase resonant converter arrangement with series dual phase in the primary side and parallel dual current doubler in the secondary side, operating as a phase shift controlled current source is presented. Sharing the voltage and current stress among the active and passive components with a high DC input voltage and arc current motivates this structure, which also uses WBG devices to increase the efficiency at high switching frequency. The resulting module is intended to operate in continuous and pulsating mode and can be parallelized to extend the output arc current rate.

“…However, a large-size core is required to eliminate the thermal problem. The energy stored in the magnetizing inductance can also be used to extend the ZVS range, but this causes significant increase in the conduction loss [8]- [9]. In the approach proposed in [10], full load range ZVS of switches are achieved by using a simple LC auxiliary circuit with a minimal duty-cycle loss and secondary-side parasitic ringing.…”

An improved full-bridge (FB) pulse-widthmodulated (PWM) converter is proposed featuring zero-voltageswitching (ZVS) of all primary switches in the entire line and load range. Compared to the conventional full bridge dc/dc converter, the proposed converter achieves ZVS with substantially reduced duty-cycle loss and circulating current. The operation principle of the circuit is described and design considerations of the converter are discussed. Finally, the operation and performance of the proposed converter is verified on a 1-kW (54-V/20-A) experimental PWM FB converter prototype operating at 100 kHz from a 300-400 V dc input.
