Predictive power control of an AC/DC/AC converter

Fourtieth IAS Annual Meeting. Conference Record of the 2005 Industry Applications Conference, 2005., 2005
This paper presents a new control scheme for a regenerative AC/DC/AC converter using model based predictive control. The control strategy minimizes quality functions, which represent the desired behavior of the converter. At the inverter side, the load current error is minimized, while at the input side, the active and reactive powers are controlled ...

Novel bidirectional DC-DC-AC three-phase power converter

2013 IEEE Power and Energy Conference at Illinois (PECI), 2013
This paper proposes a dc-dc-ac three-phase converter in order to interface dc and ac variables allowing a bidirectional power flow. A direct application of this converter is in Vehicle-to-Grid (V2G) system and interfacing dc microgrid with three-phase utility grid.

Monte Carlo simulation of AC/DC/AC power converter distortion

2001 IEEE Porto Power Tech Proceedings (Cat. No.01EX502), 2002
Probabilistic analyses of AC/DC/AC power converter harmonic and interharmonic distortion are performed by using the Monte Carlo simulation. Starting from previous experiences of some of the authors, an analytical and simplified conversion system model recently proposed is recalled and discussed. A new model of the control system is presented. Different

Novel regulated DC/DC and DC/AC power converters

International Journal of Renewable Energy Technology, 2009
Power sources with a desired voltage profiles, are required in many applications including renewable energy. Although in most cases, a sinusoidal waveform of specified amplitude and frequency is of interest, other types of voltage profiles, such as square, trapezoidal, triangular, etc., may also be required in amplifiers, shakers, mechatronics, etc ...

Comparison of High-Power DC/AC Converters for Medium-Voltage PV Power Plants

2023 Asia Meeting on Environment and Electrical Engineering (EEE-AM), 2023
In the last decade, the total photovoltaic (PV) power installed in the world has been increasing signifi cantly; and PV plants of hundred megawatts are nowadays in operation. In order to reduce material consumption for the construction of PVsystems, a shift to Medium-Voltage power plants is envisaged. In this paper, a comparative study of high-power DC/

Soft switched capacitively coupled DC-AC converter for high power

Conference Record of the 1993 IEEE Industry Applications Conference Twenty-Eighth IAS Annual Meeting, 2002
A capacitively coupled DC-AC power converter which is capable of zero current soft switching is presented. A form of amplitude modulation is introduced to provide a sinusoidal output waveform. Due to its favorable current stresses on the switches, this converter is suitable for high current high power inductive load applications.

Parallel DC/AC Converters under Connection/Disconnection of Power Modules

2012 VI Andean Region International Conference, 2012
Paralleling converters is normally employed to increase power capacity in different applications, such as autonomous micro grid systems and unininterruptible power supplies. These systems share the current between the different converters, but it must be in an equalized manner, no matter different type of loads or conditions.

PSO optimal tracking control for a DC-AC power converter

2014 World Automation Congress (WAC), 2014
This contribution presents an infinite-horizon optimal tracking controller for nonlinear systems based on the state-dependent Riccati equation approach. The synthesized optimal control law comes from solving the Hamilton-Jacobi-Bellman equation for state-dependent coefficient factorized nonlinear systems.

AC/DC/AC converter in a small hydroelectric power plant

Bulletin of the Polish Academy of Sciences: Technical Sciences, 2011
AC/DC/AC converter in a small hydroelectric power plant The article discusses application of AC/DC/AC converter cooperating with an induction generator in small hydroelectric power plants. The induction generator works with power grid or a separated group of receivers, enabling to generate power even at low speeds of the turbine.
