Capacitors for IGBT
As a result of many years of research on the modernization of technology MKK, Inc. EPCOS AG introduced its power electronics imeeschee not unique high-tech and high-quality product that fully complies with all current requirements - new series capacitors PCC HPTM (Power Capacitor Compact, High Power). These capacitors are specially designed to be mounted directly to the output terminals of IGBT inverter. The modular design and a special connector between IGBT and PCC HPTM provides a nominal capacity that ensures low inductance circuit and the smooth operation of all types of IGBT inverters. No more having to install additional battery decoupling capacitors, complicating the design and weighting of the power module.
In the development of this series focused on improving the reliability, reduce the cost and increase the service life in the most extreme conditions. Sealed PCC HPTM the capacitor is made of stainless steel and glass-fiber reinforced polyester. This design ensures that no drift capacity with temperature, and meets all standards of fire.
The capacitor does not require maintenance (up to 5 years of continuous operation), and is safe in operation. Precautions to prevent the leakage of oil, with the means of monitoring sensors, fire and explosion, regular preventive and emergency maintenance - no longer required, if selected for the new development series capacitors PCC HPTM. The main areas of application · IGBT Inverter (electrical transport, aviation, mining, etc.) · Electric Industrial (SIV, SVG) · powerful source of pulsed current (pulse generator, laser welding machine, switching power supply) · Increased Benefits lifespan. · Very low self-inductance (less than 40 nH). · High current capacity (over 300 A). · Lack of self-discharge. · Compact housing made of stainless steel, light weight · No need for service · Dry technology (no oil) · Self-Healing (technology SH) · Non-flammable materials (standard NFF).
