Since the first-stage ceramic capacitors have a triangular ripple voltage, Equation 3 gives the second-stage inductor ripple current as: Using an attenuation factor of 20%, the inductor peak-to-peak ...

(3) Thus, the input capacitor conducts a square-wave current of peak-to-peak amplitude Io and it follows that the resultant capacitive component of AC ripple voltage is a triangular waveform with peak ...

Abstract:An ultra-low ripple traveling wave tube cathode power supply is introduced in this paper, achieving the secondary suppression of the high-voltage output ripple by linear voltage regulator ...
