Based on the traditional indirect matrix converter topology dual input dual output indirect matrix converter is proposed, but the conventional six-switch inverter, used in the singleoutput indirect matrix converter, is replaced by a nineswitch dual output converter. The matrix converter has several advantages over traditional rectifier-inverter type power frequency converters. It provides sinus...

An inductorless switched capacitor (SC) DC-DC voltage converter and a model based on the averaging technique are presented. The model was validated through circuit level simulations for a SC converter designed using CMOS 0.18 um technology, capable to deliver output currents up to 100 mA at a regulated low ripple 3.3 V output voltage, for input voltages between 1.8 V and 3.2 V and can be used f...

In this work, a non-isolated high step up DC-DC converter using coupled inductor and voltage multiplier cell is proposed. The proposed converter conversion ratio is efficiently extended by using a coupled inductor. An interleaved configuration of two diode-capacitor cells is applied to step up the voltage conversion ratio and decrease the voltage stress across the switches. Also, in the suggest...

A single-inductor dual-output (SIDO) DC–DC buck converter is presented. The circuit uses only one (external) inductor to provide two independent output voltages ranging from 1.2 V to the power supply (2.6–5 V) with a maximum total output current of 200 mA. The proposed converter has been fabricated in a 0.35-lm p-substrate CMOS technology. Measurement results demonstrate that a peak power effic...

In this paper, a simple yet efficient auto mode-hop ripple control structure for buck converters with light load operation enhancement is proposed. The converter, which operates under a wide range of input and output voltages, makes use of a state-dependent hysteretic comparator. Depending on the output current, the converter automatically changes the operating mode. This improves efficiency an...

This paper presents a novel sparse matrix converter configuration that needs no bulky energy storage capacitors or inductors, and employs only unidirectional power semiconductor switches. The source side bridge is switched at the line frequency and therefore, this allows the use of the low speed high power rating switches. This feature and the use of diode-clamped multilevel topology at the out...

Design-oriented analysis of switching converters must take into account how disturbances and variations in the input and control signals affect the optimum performance of these converters. Sate-space averaging of a nonideal boost converter is presented in this paper. DC state and small signal AC state modeling of the converter was derived. Determination of line-to-output transfer function, whic...

This thesis describes the design and construction of a 250 W, 35-60 Vin, 5 Vout dc-dc power converter with a switching frequency of 500 kHz. The converter uses square wave switching and is composed of two power processing stages in series. The first stage, a boost converter, regulates the output voltage of the converter. The second stage, a push-pull converter operating at 100% duty-cycle, prov...

In this paper, a 0.18-V input three-stage charge pump circuit applying forward body bias is proposed for energy harvesting applications. In the developed charge pump, all the MOSFETs are forward body biased by using the inter-stage/output voltages. By applying the proposed charge pump as the startup in the boost converter, the kick-up input voltage of the boost converter is reduced to 0.18 V. T...
