In the realm of medium/high voltage applications, the modular multilevel converter with an active power filter (APF-MMC) emerges as a technology that eliminated the inherent voltage fluctuations of larger sub-module (SM) capacitors. However, the introduced APF circuit in each phase can only deal with power in even frequencies, and the APF-MMC cannot
With the values shown above (C = 47 pF, L = 20 nH), equation (1.3.5) gives a series resonant frequency of 164 MHz, which is very close to the resonant dip shown in Figure 1.9.We can conclude, therefore, that even a small lead inductance, like 20 nH, will have an adverse effect on the performance of the leaded capacitor.We therefore tend to use SMD "chip" capacitors

In the capacitive characteristic region, the larger the capacitance, the lower is the impedance. Moreover, the smaller the capacitance, the higher is the resonance frequency, and the lower is the impedance in the inductive characteristic region. Our explanation of the frequency characteristics of capacitor impedance may be summarized as follows.
Equivalent high frequency capacitor model. This means that the important characteristic distinguishing different capacitors for different frequency ranges is the capacitor’s self-resonant frequency. At this particular frequency, the capacitor will exhibit its minimum impedance and a very strong current response.
In other words, the self-resonant frequency should be greater than the knee frequency. With high frequency analog signals, any capacitors should be chosen such that the relevant frequencies in the system are lower than the self-resonant frequency.
At low frequency, the impedance provided by the capacitor is dominant, and your capacitor will exhibit close to ideal behavior. At sufficiently high frequency, the ESL value takes over, and the impedance starts to appear inductive. This produces an effect known as self-resonance at just the right frequency.
With high speed digital signalling, capacitors should be selected such that they have ideal capacitive impedance up to the signal’s knee frequency (0.35 divided by the 10%-90% rise time). In other words, the self-resonant frequency should be greater than the knee frequency.
