GDHY C32 capacitor discharge welder snubber capacitor series for IGBT snubber

The structure of the absorption capacitor (also can be capacitor dischagre welder) is characterized by double-sided metallized polypropylene film inner string structure, special internal design and end-face gold spray technology, so that the capacitor has low inductance, multiple lead designs such as tinned copper lugs, tinned copper wire leads,copper nut leads, can withstand higher ripple current, high DU/DV and High overpressure capability. Flame retardant plastic shell, epoxy resin encapsulation, in line with UL94V-0 standard. It is used for various IGBT buffer circuit surge absorption, various high frequency resonance circuits. It is also used in the output of Class-D audio amplifiers. A snubber network damps the ringing and overshoot due to fast switching of high currents. When the transistor you use to switch the current turns off, it generates a high-voltage spike that could damage the device.This spike will also generate electromagnetic interference (EMI). Be aware that EMI is caused by current in a loop. If your snubber network routes current in a large loop, it will increase rather than reduce EMI.

A snubber capacitor is designed to increase the circuit's performance, but it also increases the IGBT's ability to exploit high-speed switching capabilities more efficiently, potentially allowing for even high-frequency control. A high-performing capacitor is ideal for use in a high-performance, high-power circuit as it must be able to cope with its challenging system effects as well. Capacitor discharge for welder, induction heaters, DC welding machines plays a important role in the industry.
