Audiosusceptibility – determines the transmission of noise from input to output. Input impedance – determines the sensitivity of the power system to input filter or input power system components. The first two parameters, loop gain and output impedance, were discussed in the first article of this series.

important changes of the audio susceptibility near the null value. As we can see from Fig. 4b, for Mc<1.5, the transfer function phase of audio susceptibility starts from 180 o. When the null value is reached (Mc=1.5), the phase will start from 0 o. That means we are in the null area of the audio susceptibility. Frequency

Audio-susceptibility transfer functions without and with feed-forward gains along with required power-stage transfer functions are derived for peak current-mode controlled PWM dc-dc buck converter. The derived audio-susceptibility transfer functions are illustrated for given values of perturbation ratio using MATLAB.

RTCA DO-160 – Section 18.0 – Audio Frequency Conducted Susceptibility – Power Inputs This test determines whether the equipment will accept frequency components of a magnitude normally expected when the equipment is installed in the aircraft. These frequency components are normally harmonically related to the power source fundamental frequency.

Abstract: In this paper, the audio susceptibility characteristic of a high-efficiency nonisolated topology that processes only a part of the total power delivery is analyzed. Since the proposed topology presents a direct path from input to output, the effect of the input voltage ripple at the output voltage has been studied.

audio susceptibility and input impedance must be taken into account. Take PCU for example, when the solar array supplies energy to the dc load and battery through battery charge regulator (BCR), the bus voltage is regulated by sequential shunt switching regulator with hysteresis control strategy [18, 19]. Hence, the input voltage of BCR presents
