A Power Supply for Welding machine of Reducing Conduction Losses
초록
This paper proposes a power supply for welding machine of reducing conduction Losses. To improve the conventional Phased-Shift FB DC-DC converter's problems that the copper loss in the high frequency transformer and conduction losses in the 1st terms bridge switch device because the leakage energy in the high frequency transformer and inducing of circulating current. This paper suggested a new topology of FB PWM DC-DC converter for welding machine to minimize a circulating current.
