“…Individual inductor current ripples are neutralized, lowering the overall ripple current that flows through the output capacitor. The output voltage ripple can be greatly reduced with such ripple cancellation [15]. The current ripple going into the output is minimized when the inductor current is cancelled, requiring a reduced capacitance to meet the very same output voltage ripple demands [14].…”

<p>Modern microprocessors in high-power applications require a low input voltage and a high input current, necessitating the use of multiphase buck converters. As per microprocessor computing complexity, the power requirements of the switching converter will also be more important and will be increasing as per load demand. Previous studies introduced some methods to achieve the advantages associated with multiphase regulators. This paper presents an effective closed closed-loop control scheme for multiphase buck converters that reduces ripple and improves transient response. It is suitable for applications that require regulated output voltage with effectively reduced ripple. The analysis began with a simulation of the entire design using the OrCAD tool, followed by the construction of a hardware setup. Experiments on a 200 Khz, 9 V, 12 A, 2-phase buck voltage regulator were conducted and the proposed experiment found to be useful.</p>

“…This paper describes how to attain stability via analysing the loop. The open-loop gain/phase response (the transfer function) of the entire chain is examined using a bode plot, and the transfer function is shaped using the closed loop compensation to balance the converter across a range of input/output configurations [15].…”
