Fast controller for a unity-power-factor PWM rectifier

This paper describes practical modeling and simulation techniques of general-purpose system Analog simulators which can analyze a power electronic (PE) Mechanical system which is mixed in three meanings; analog and Rotational Thermal digital, main and control, and multiple physical domains. First it is described how to model the mixed system by decomposing it into different classification Physical types in a system description language, for example, (Conservative) in AHDL or in VHDL-AMS. It is also described how Main it is briefly processed numerically by simulators. SecCircuits ondly linking methods with other modules, for exam-AL ple, with a C module, are described to extend the Gate Sensor analyzable circuit class. Finally two analysis and deSignal sign examples are described. A digitally controlled inverter system is adopted to show how a mixed PE Control Signal-Flow system is modeled. A digitally-controlled converter Circuits system with a FPGA and a DSP units is also described to show how the simulation is effectively used for pracDiscrete

“…Moreover, high-speed and high-accuracy microcontrollers and digital signal processors (DSPs) are available at reasonably low cost. Many processors are developed to give direct PWM outputs with fast software [69], [82], [140] normally used in some of these converters, which reduces hardware drastically. With these processors it is now possible to implement new and improved control algorithms of real-time control to provide fast dynamic performance of IPQCs.…”

Abstract-Solid-state switch-mode rectification converters have reached a matured level for improving power quality in terms of power-factor correction (PFC), reduced total harmonic distortion at input ac mains and precisely regulated dc output in buck, boost, buck-boost and multilevel modes with unidirectional and bidirectional power flow. This paper deals with a comprehensive review of improved power quality converters (IPQCs) configurations, control approaches, design features, selection of components, other related considerations, and their suitability and selection for specific applications. It is targeted to provide a wide spectrum on the status of IPQC technology to researchers, designers and application engineers working on switched-mode ac-dc converters. A classified list of more than 450 research publications on the state of art of IPQC is also given for a quick reference.

“…A decision process of the current reference characterizes a control performance of the corrector [6]. In order to improve the performance, for example, the reference is characterized by a feedforward loop as a source voltage feedforward [7][8][9][10] and a load current feedforward [3]. A reference model to generate the current reference is also proposed on a basis of an inverse dynamics of a linearized model of the corrector [11].…”

SUMMARYA nonlinear controller for a power factor corrector is systematically constructed via Lyapunov-based controller design approach for the bilinear state averaged model. First, a nonlinear gain of the controller is derived to shape the source current and the output voltage be desired form respectively via nonlinear H 1 control system design approach. Second, a source current reference generator is constructed, which consists of a current feedforward loop given by a steady state analysis and a voltage feedback loop with an output voltage error amplifier. The design approach makes it clear that the tracking performance for the output voltage is achieved by generating an adequate source current reference. This paper finally shows efficiencies of the approach through computer simulations.
