AC choppers are a family of ac-to-ac power converters that can be derived from the traditional dc-to-dc converters. Research activity in this kind of converter has recently increased in applications for power conditioning - such as voltage control in the distribution system and power flow control in the transmission system - as an alternative for the dc-link approach compensators based on voltage source converters. The control is simpler and the power rating of the devices is smaller for compensators with the same power rating; the main drawback is they cannot control the output-voltage frequency as the matrix converter. This paper presents a state-of-the-art review on the development of ac-choppers. The principle of operation is explained by using the six switches three-phase buck converter as an example. The main applications used in power conditioning and power flow control are introduced along with emerging topologies. ©2010 IEEE.

This letter proposes a boost dc-dc converter topology with the novel capability of canceling the input current ripple at an arbitrarily preselected duty cycle. This is accomplished without increasing the count of the number of components in contrast to other solutions available in the literature. In addition, the converter features a high voltage gain without utilizing extreme values of duty cycle or boosting transformers. These features make the converter ideal to process electric power coming from low-voltage power-generating sources, such as renewables. This paper provides details on the principle of operation via topological considerations and a mathematical model. The key factor of reactive component sizing is also discussed in detail. The converter was validated in the laboratory through the construction of a hardware prototype. © 1982-2012 IEEE.

This paper shows the design and implementation of a Fuel Cell (FC) system emulator through the Hardware-in-loop (HIL) technique. The proposed FC emulator is tested on a detailed nonlinear simulator taken from the open literature. The goal of this research is the setup of a test bench that allows developing and testing control strategies in a FC system as well as to dispose with a platform for developing new power conditioning converters for this kind of systems. The Proton Exchange Membrane Fuel Cell (PEMFC) is the class of FC addressed in this research. The emulator is based on an interleaved buck converter in order to get a test bench with an output voltage of good quality. © 2012 IEEE.

Static quadrature phase shifters controlled by pulse width modulation allow controlling the power flow in a transmission line by introducing a phase shift between sending and receiving voltage nodes. This work proposes a PWM quadrature phase shifter which uses only two driven switches which is advantage again current topologies that use six or four switches. As other AC-link converters, the PWM control is based on DC signals asynchronous from the grid, free of PLL and trigonometric calculations, this also makes frequency and phase perturbation don't affect the pulse width modulation as in the traditional PLL-synchronized SPWM, while the control can be accomplished with a low-cost micro controller, simulation and experimental results are shown to prove the principle of the proposition. © 2010 IEEE.

The dc-dc multilevel boost converter topology was recently proposed with features such as high voltage gain without using an extreme duty ratio, few components and self dc-link balancing. This paper presents the state space modeling and a linear controller based on the pole placement technique for the dc-dc multilevel boost converter. Nonlinear and linear models are derived. Simulation results obtained with the averaging model in Matlab and with the simulated circuit in Synopsys Saber software are presented to prove the principle of the proposition. ©2010 IEEE.

This study proposes several dynamic models for a DC-DC multilevel boost converter. A full-order non-linear dynamic model, a reduced-order non-linear model and a small-signal model are derived. These models are based on the equivalent circuits that depend on the switching states of the converter. In addition, an input-output feedback linearisation controller is derived and implemented. The stability of the closed-loop system is analysed. A Linux-based real-time software is employed for obtaining the experimental results of the closed-loop system. © 2011 The Institution of Engineering and Technology.

This work introduces a set of PWM SEPIC dc-dc converters specially designed for high voltage-gain conversion, the voltage gain in the proposed converters can be adjusted by PWM and by adding diodes and capacitors in a diode-capacitor multiplier structure. They main features are: (i) high-voltage gain, without extreme duty cycles and transformer-less which allow high switching frequency and without cascaded connection, (ii) low voltage stress in switching devices, along with modular structures, and more output levels can be added without modifying the main circuit, which is highly desirable in some applications such as renewable energy generation systems (iii) it posses only one switch and two inductors, the voltage gain can increases by adding only diodes and capacitors. In addition, an average dynamic model is proposed for this converter. A detailed theoretical analysis is given. Both simulation and experimental results are provided to verify the principle of operation. © 2011 IEEE.
