Low Power Losses Configuration for DC/AC Converters

2006
A high efficiency converter topology is proposed in this paper. It has been designed and implemented for a particular application, in which the converter has to work in very critical external condition, such as anti-fire systems. The features to be achieved are the following: dc/ac conversion from a low voltage input source and a minimization of the ...

DC-AC photonic power converters with liquid crystal optical modulators

Optics Letters
In this Letter, we propose a power-switch-free (PSF) DC–AC photonic power converter (PPC) that utilizes liquid-crystal optical modulators (LCOMs) to commutate optical flux, thereby eliminating the need for power switches and avoiding switching-induced electromagnetic interference (EMI).

High power DC/AC/DC converter based on different modulation strategies

2016 IEEE 8th International Power Electronics and Motion Control Conference (IPEMC-ECCE Asia), 2016
The recent researches on high voltage and power DC/DC converter mainly focus on topology. The newest topology based on modular multilevel converter(MMC) is composed of a transformer coupling two three-phase MMC, so that it can be easily extended according to the required voltage rating.

Transformerless DC/AC Converter for Grid-Connected PV Power Generation System

Arabian Journal for Science and Engineering, 2014
Transformerless photovoltaic (PV) systems have two shortcomings: low voltage not fulfilling load requirement and ground-leakage current flowing through parasitic capacitance between the PV panel and ground. Therefore, a DC/AC converter—a single-phase bipolar sinusoidal pulse width modulation (SPWM) H-Bridge power inverter configuration with a DC/DC ...

High power factor AC/DC/AC converter with random PWM

IEEE Transactions on Aerospace and Electronic Systems, 1999
A three-phase AC/DC/AC converter is presented with a power factor preregulator to improve the power quality in the input side and a pseudorandom noise generator to reduce the emitted acoustic noise and the mechanical vibration for an induction motor drive.

Linear Control Approaches for DC-AC and AC-DC Power Converters

2013
This chapter addresses linear techniques for controlling the average (low-frequency) behavior of power electronic converters that include not only DC but also AC power stages. Without being exhaustive, the chapter focuses on the most-used control methods applied to somewhat popular single-phase and three-phase PWM- or full-wave-operated power ...
