Input-Constrained Current Controller for DC/DC Boost Converter

This paper presents a simple input-constrained current controller for a DC/DC boost converter with stability analysis that considers the nonlinearity of the converter model. The proposed controller is designed to satisfy the inherent input constraints of the converter under a physically reasonable assumption, which is the first contribution of this paper. The second contribution is providing a ...

An Integrated CMOS DC-DC Converter for Battery-Operated Systems

Abstract -This paper presents an optimum design for low-voltage, low-power DC-DC converter which has a controller and integrated CMOS switches using small size inductor (luH). Optimum design for single chip DC/DC converter is achieved by analyzing the amount of conduction and switching losses. Through the loss analyses, it is turned out that a constant frequency hard switching PWM converter wit...

A Bi-Directional DC/DC Converter for Energy Storage Systems

This paper addresses a bi-directional dc/dc converter suitable for an energy storage system with an additional function of galvanic isolation. An energy storage device such as an electric double layer capacitor is directly connected to one of the dc buses of the dc/dc converter without any chopper circuit. Nevertheless, the dc/dc converter can continue operating when the voltage across the ener...

Design of a CMOS DC-DC Converter -Adaptive CMOS DC-DC Converter for a Portable Battery Powered Systems-

Abstract In this paper, we describe a CMOS DC-DC converter with a variable output voltage (8-12V @100mA) for a portable battery-operated system applications. The proposed DC-DC converter is used along with a Pulse-Frequency Modulation (PFM) method and consists of a reference circuit, a feedback resistor, a controller, and an internal oscillator. The integrated DC-DC converter with two external ...
