With the evolution of power technology, new higher speed Insulated Gate Bipolar Transistors (IGBTs) make it possible for high power inverters to operate up to 20 kHz or more. IGBTs are replacing the slower Darlington transistors, simplifying circuit design and reducing end product cost. IGBT power modules are now being designed into AC and DC motor drive inverters, uninterruptible power systems, electric vehicles and alternative energy production systems. Power systems containing IGBTs must be designed so the transient voltage caused by the high di/dt that occurs at gate turn off is minimized. Left uncontrolled, this transient voltage can exceed the blocking voltage rating of the IGBT and cause it to fail. To reduce the transient voltage, either di/dt or the parasitic DC bus inductance of the power circuit must be reduced. This is best achieved by decoupling the parasitic bus inductance using a non-inductive wound film capacitor mounted as near as possible to the IGBT modules terminals. Snubber capacitors, constructed of polypropylene film dielectric and dual metallized film electrodes, are the optimal capacitor design for IGBT applications. While film/foil capacitors are often used because of their superior current carrying capability, they fail in a short circuit mode which may cause damage to the IGBT module. Aerovoxs snubber capaci- tors combine high current carrying capability with low inductance, low dielectric losses, and capacitance stabil- ity across a wide frequency range. They offer the self-healing property of metallized film (not failing in a short circuit mode) with the high peak current carrying capability (dv/dt) of film/foil construction. Aerovoxs snubber capaci- tors, manufactured with polypropylene film and dual metallized electrodes, available with direct IGBT module terminals, radial wire leads, or a unique printed circuit board dual in-line pin mount, provide the highest electrical performance of any snubber capacitors currently available.
