It's widely produce DC-link capacitors, filter capacitors, snubber capacitors, coupling capacitors, AC filter capacitor, compensating capacitor and so on, power supply, plating power supply, UPS, induction heating machine and other kinds of electronic equipments.

Used for buffering absorption, high pulse line, MOSFET buffering absorption, high frequency resonant voltage.

The busbar inductance and the stray inductance in the buffer circuit and its components have great influence on IGBT circuits, especially the high power IGBT circuits. Therefore, the smaller the better. To reduce these inductances, we need to start from many aspects.

1. The DC bus should be as short as possible;
2. The buffer circuit should be as close to the module as possible;
3. Polypropylene electroless capacitor with low inductance, fast buffer diode matched with IGBT, and non-inductive discharge resistor are selected.
4.  Other effective measures. Buffer circuit production process also has a variety of ways: useful discrete parts connected; Connected by a printed plate; More useful buffer capacitor module directly installed on the IGBT module. Obviously, the last way is in line with the above second and third measures to reduce sensation, so the buffer effect is the best, can maximize the protection of IGBT safe operation.
