Optimization of Metalized Film Capacitor Connection to Reduce Stray Inductance [PDF]
IEEE Transactions on Components, Packaging and Manufacturing Technology, 2019 In power electronic applications, due to switching components, the inverter dc-bus generates current pulses at low frequencies and high frequencies (HFs). Usually, a dc-bus capacitor is sized to absorb the current peaks at the switching frequency and to stabilize the dc voltage. For decoupling the HF harmonics, an additional capacitor is required. This
