An Integrated Silicon Carbide (SiC) Based Single Phase Rectifier with Power Factor Correction



I. INTRODUCTION
Power supplies are one of the most crucial building
blocks of a modern society, converting high-voltage AC
into low-voltage DC for use in electronic circuitry in office
equipment, telecommunication, and consumer electronics.
Over 2.5 billion AC/DC power supplies are currently in use
in the United States alone, about 6 to 10 billion are in use

A Single-Phase High Power Factor Rectifier,
Based on a Two-Quadrant Shunt Active Filter



Abstract

This paper presents a new technique to improve the
input power factor of a single-phase rectifier followed by an
inductive filter. It consists in the employment of a two-quadrant
active power filter, based on a conventional bidirectional DC-DC
converter, connected to the output side of the diode bridge. This
technique allows the extension of this rectifier range operation in
the continuous conduction ....etc

ABSTRACT

In this paper a new single phase to three-phase converter for ac motor is proposed. The proposed converter employs only six switches and incorporates active input current haping feature, which results in sinusoidal input current at close to unity power factor. The front-end rectifier in the proposed converter permits bidirectional power flow and therefore provides for excellent regulation against fluctuations in source voltage. This feature also facilitates regenerative braking of ac motor drive. An easy to implement control stra ....etc

Abstract
An active current injection network for a three-phaserectifier is proposed. The proposed circuit uses three bidirectionalswitches operating at low frequency and a half-bridge inverteroperating at high frequency. It also uses an inductor in orderto make the current modulation. Because only 3.7% of the totalpower delivered to the load is processed by the injection network,the proposed converter offers high efficiency, and not only a highpower factor is obtained but also the total harmonic distortion isreduced. Operation, analysi ....etc

Abstract
This paper presents an analytic current model for capacitively coupled Single-Electron Tunneling Transistors (SETTs) that is based on a modified M-state steady-state master equation. Based on this current model we also derive a current noise model for SETT. To validate the proposed models we calculate their characteristics at different device parameters and different operation temperatures and compare them with the corresponding characteristics calculated by the full master equation method. The results indicate that the propo ....etc

ABSTRACT
A high-frequency electrical resonance-based ignition concept
is in development to replace conventional spark ignition
functionality for gasoline engines employing various types of
fuel injection methods. The concept provides the benefit of a
continuous discharge phase and the electrical power of the
discharge can also be adjusted to the needs of the combustion
conditions.
This concept employs an alternative method of generating
high voltages, using inductors and capacitors trimmed such
that the supplied energy steadil ....etc
