A 16-blt oversampllng D/A converter has been designed uslng a 4'th order all-dlgltal noise-shaping loop followed by a 3-blt D/A converter. The 3-blt D/A converter, which employs a novel form of dynamlc element matchlng, achleves hlgh accuracy and long-term stablllty without requlrlng preclslon matchlng of components. The harmonic dlstortlon of the untrimmed monolithic CMOS prototype D/A convert...

LLC (Inductor-inductor-capacitor) resonant converter has lots of advantages over other type of resonant converters which include high efficiency, more reliable and have high power density. This paper presents the design and analysis of a full bridge LLC resonant converter. In addition to the operational principle, the ZVS and ZCS conditions are also explained with the DC characteristics. Simula...

A Power Factor Correction Using singleinductor dual-output buck-boost converter operating in critical conduction mode is proposed in this paper. Each output of the SingleInductor Dual-Output buck-boost converter can be regulated independently by multiplexing a single inductor, Compared with a conventional two-stage multiple-output converter, the singleinductor dual-output buck-boost converter b...

The paper presents a unified steady-state analysis of PWM SEPIC converter with coupled inductors and separate inductors for both continuous and discontinuous conduction modes. The results of this simplified analysis allow to determine the operating point of converters and further the small-signal low-frequency parameters of linear model, and to design the converter too.

The paper focuses on a DC/DC converter that is used to adapt a varying output voltage from a solar panel to demands of an electrolyzer unit or battery charging purposes. The converter covers an input voltage span from 9 V to 24 V and has an output voltage of 12 V at a maximum current of 50 A. A modular topology of the converter is described along with a microcontroller control strategy. Finally...

This paper presents a high-efficiency nonisolated interleaved dc–dc inductor boost converter with a common active clamp circuit. Interleaved boost converters are highly preferred as it reduces the ripple current. A boost converter is used to clamp the voltage stresses of all the switches in the interleaved converter which is caused by the leakage inductances. The leakage energies of the interle...
