TL;DR: In this paper, a method for providing adaptive compensation for an electrical circuit where the electrical circuit includes an inductor-capacitor network connected in a feedback loop being compensated by a first compensation capacitance value and a second compensator value defining the frequency locations of two compensation zeros is proposed.
Abstract: A method for providing adaptive compensation for an electrical circuit where the electrical circuit includes an inductor-capacitor network connected in a feedback loop being compensated by a first compensation capacitance value and a second compensation capacitance value defining the frequency locations of two compensation zeros includes: measuring the inductance value of the inductor; when the inductance value is greater than a first threshold value, increasing the first and second compensation capacitance values so that the frequency locations of the two compensation zeros are adjusted for compensating the poles introduced by the first inductor and the first capacitor; and when the inductance value is less than the first threshold value, decreasing the first and second compensation capacitance values so that the frequency locations of the two compensation zeros are adjusted for compensating the poles introduced by the first inductor and the first capacitor.

TL;DR: A fully integrated capacitive step-down DC-DC converter in 90 nm CMOS with an output power capability of 150 mW, a peak efficiency of 77% and a full load efficiency of 74%.
Abstract: Monolithic integration in CMOS has boosted the development of low cost, compact and portable consumer applications. But until now the monolithic integration of DC-DC converters is still omitted in commercial applications. Primarily due to the need for high-efficiency converters and appropriate techniques to control high-frequency capacitive DC-DC converters. This paper presents a fully integrated capacitive step-down DC-DC converter in 90 nm CMOS with an output power capability of 150 mW, a peak efficiency of 77% and a full load efficiency of 74%. The DC-DC converter is controlled by a Single Boundary-Multiphase Control (SB-MC). This control method provides a low power solution for controlling multiphase capacitive DC-DC converters without compromising the control loop bandwidth. This paper describes the design, implementation and measurements of the DC-DC converter.

TL;DR: A circuit technique that reduces the boost power converter losses caused by the reverse-recovery characteristics of the Rectifier by inserting an inductor in the series path of the boost switch and the rectifiers to control the di/dt rate of the rectifier during its turn-off.
Abstract: A circuit technique that reduces the boost power converter losses caused by the reverse-recovery characteristics of the rectifier is described. The losses are reduced by inserting an inductor in the series path of the boost switch and the rectifier to control the di/dt rate of the rectifier during its turn-off. The energy from the inductor after the boost switch turn-off is returned to the input or delivered to the output via an active snubber. The same technique can be extended to any member of the PWM power converter family.

TL;DR: In this paper, the complex admittance of a four-element circuit is calculated and compared with measurements on two typical CIGS solar cells, and the model circuit consists of a capacitance C in parallel with a resistance r, with this combination in series with a resistor R and inductor L C accounts for the depletion capacitance of the diode, and R and r account for series and shunt resistances typically observed in solar cell current-voltage measurements.

31 Jan 2006TL;DR: In this article, a ladder-shaped magnetic core was proposed for the buck converter with the ladder structure, where the inductors extended under and over opposite sides of the toroidal magnetic core and had a relatively low ohmic resistance.
Abstract: A multiple phase buck converter or boost converter, or buck-boost converter has an inductor in each phase. The inductors are inversely coupled. In a first embodiment, the converter includes a toroidal magnetic core with inductors extending under and over opposite sides of the toroidal magnetic core. The coupled inductors are thereby inversely coupled and have a relatively low ohmic resistance. In a second embodiment, the converter comprises a ladder-shaped magnetic core (i.e. having parallel sides, and connecting rungs). In this case, the inductors extend under the sides, and over the rungs. Each inductor is disposed over a separate rung. The ladder-shaped magnetic core is preferably disposed flat on a circuit board. Inverse coupling and low ohmic resistance are also provided in the second embodiment having the ladder structure.
