When either the input or output stage reactors are considered in series with the shunt network, the natural resonant frequency is now forced to be near the 4th harmonic due to the larger total inductance (L). This means the APQ low pass harmonic filter will not cause harmonic resonance problems. The ...

Bode plot
In electrical engineering and control theory, a Bode plot /ˈboʊdi/ is a graph of the frequency response of a system. It is usually a combination of a Bode magnitude plot, expressing the magnitude of the frequency response, and a Bode phase plot, expressing the phase shift. Both quantities are plotted against a horizontal axis proportional to the logarithm of frequency.
