Why Use Snubber Capacitors?With the evolution of power technology, new higher speed Insulated Gate Bipolar Transistors (IGBTs) make it possible for high power converters to operate up to 10 kHz or more. IGBTs are replacing the slower Darlington transistors, simplifying circuit design and reducing cost. IGBT power modules are now being designed into AC and DC motor drive inverters, uninterruptible power systems, electric vehicles and alternate energy production systems. Power systems containing IGBTs must be designed so the transient voltages caused by the hi 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 module terminals. Snubber capacitors, constructed of polypropylene film dielectric and aluminium foil plus metallised polypropylene film, 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. El-Ci-Ar’s snubber capacitors combine high current carrying capability with low inductance, low dielectric losses and capacitance stability 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.
