Captop 400 Amps i Gray Heavy Duty Igbt Modular Welding

It converts direct current into high frequency square wave alternating current, with the low frequency direct current coming out rectified by the high frequency transformer at the output. A resistor capacitance connected in parallel at both ends of IGBT is the network for absorption of the base peak voltage.IGBT stands for insulated-gate bipolar transistor. Figure (a) shows the symbol of an IGBT. It is a power transistor that combines an input MOS and an output bipolar transistor.IGBT improves dynamic performance and efficiency and reduced the level of audible noise. It is equally suitable in resonant-mode converter circuits. Optimized IGBT is available for both low conduction loss and low switching loss.
