A dynamic hysteresis control of the buck converter for achieving high slew-rate response to disturbances is proposed. The hysteresis band is derived from the output capacitor current that predicts the output voltage magnitude after a hypothesized switching action. Four switching criteria are formulated to dictate the state of the main switch. The output voltage can revert to the steady state in...

A low voltage incremental analog-to-digital converter with a pipelined architecture is presented. Using first order modulators the conversion time is significantly reduced even at low sampling rates while maintaining high resolution. The switched capacitor converter is designed to operate with a 1.8V power supply and uses three pipelined modulators. With careful design and digital correction it...

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...

In this paper, a new type of ac/ac converter is proposed. The proposed converter is capable of direct ac/ac power conversion and, except for a few small snubber elements, it does not require the use of any input inductors or a dc-link capacitor. In contrast to the matrix converter, which requires bidirectional switches, the proposed converter consists of only unidirectional switches such as ins...

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...

The future trends in microprocessor supply current requirements represent a bottleneck for next generation highperformance microprocessors since the number of supply pins will constitute an increasingly larger fraction of the total number of package pins available. This leaves few pins available for signaling. On-chip power conversion is a means to overcome this limitation by increasing the inp...

The proposed DC-DC converter has low voltage ratted MOSFET switch and is connected to PV array to get high output voltage at small duty ratios. Hen...

This paper presents first an overview of the wellknown voltage and current dc-link converter topologies used to implement a three-phase PWM ac–ac converter system. Starting from the voltage source inverter and the current source rectifier, the basics of space vector modulation are summarized. Based on that, the topology of the indirect matrix converter (IMC) and its modulation are gradually dev...
