<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>

<p>This paper presents the implementation of the buck-boost converter design which is a power electronics applications that can stabilize voltage, even though the input voltage changes. Regulator to stabilize the voltage using PWM pulse that triger pin 2 on XL6009. In this design of buck-boost converter is implemented using the XL6009, LM7815 and TIP2955. LM7815 as output voltage regulator at 15V with 1A output current, while TIP2955 is able to overcome output current up to 5A. When the LM7815 and TIP2955 are connected in parallel, the converter can increase the output current to 6A.. Testing is done using varied voltage sources that can be set. The results obtained from this design can be applied to PV (Photovoltaic) and WP (Wind Power), with changes in input voltage between 3-21V dc can produce output voltage 15V.</p>

Abstract This paper establishes the first linear regulator in a 1.2 μm CMOS silicon carbide (SiC) process. The linear regulator presented consists of a SiC error amplifier and a pass transistor which has a W/L = 70,000 μm / 1.2 μm. The feedback loop is internal and the frequency compensation network is a combination of internal and external components. As a result of potential process variation in this emerging technology, the voltage reference used at the negative input terminal of the error amplifier has been made external. With an input voltage of 20 V to 30 V, the voltage regulator is able to provide a 15 V output and a continuous load current of 100 mA at temperatures ranging from 25 °C to over 400 °C. At a temperature of 400 °C, testing of the fabricated circuit has shown line regulation of less than 4 mV/V. Under the same test conditions, a load regulation of less than 420 mV/A is achieved.
