Film capacitors are widely used in power electronics applications including but not limited to DC Link, DC output fltering, and as IGBT snubbers.
Film capacitors are widely used for DC fltering in power supplies. Their function is to smooth out the DC voltage waveform after rectifcation. As with all switching devices, IGBTs are subjected to voltage transients during turn-of operation. Voltage transients result from energy trapped in the circuit’s stray inductance.
