Simulation Approach for Active PFC Power Converters with DSP Control Scheme

A Repetitive Control- based Approach for Power Sharing among Boost Converters in DC Microgrids

In this paper a repetitive control (RC) approach to improve current sharing between parallel-connected boost converters in DC microgrids is presented. The impact of changes in line impedance on current sharing is investigated. A repetitive controller is designed and connected in series with current controller of the boost converters to control the switching signals such that by regulating of th...

Design and Implementation of Power Factor Correction (pfc) Converter with Average Current Mode Control Using Dsp

This paper presents a digital controlling method for power factor correction converter with boost structure, by applying average current controlling operation at a fixed frequency, to be used at 90-265 Vrms line voltage, based on being applied on DSP. This method which is based designing in analogue domain and converting the resulting model in to digital domain will be discussed in this paper. ...

A Virtual DSP System for Design Instruction of Power Converters

This paper describes the development of an object oriented DSP based for design and control of power converters. The testbed is developed using a Texas Instrument digital signal processing (DSP) chip for a hardware-in-theloop simulation system. The system consists of objectoriented Windows-based software written in C++ and a controller hardware system for rapid prototyping and easy testing of d...

Low-power Pfc and Forward Converters – Methods to Improve Performance

Improving Light-Load Efficiency of AC/DC Boost PFC Converters by Nonlinear Control Scheme

Power supply units (PSUs) with an equally shared load current are widely employed for data processing equipment like servers due to their advantages such as easy extension of power processing capability and simple thermal management. This paper presents a method to improve light-load efficiency by reducing load-independent losses such as capacitive turn-on and core losses and reduce the THD of ...
