A design flow for a family of DC/DC converters with integrated switches and digital controller is realized. This design flow contains simulation and hardware evaluation tools which result in a fast optimization of the converter and a fast realization on silicon. The design flow makes extensive use of tools known from a digital design environment. The design flow covers the whole range from init...

With the increasing demand for power from the ac line and more stringent limits for power quality, power factor correction has gained great attention in recent years. A variety of circuit topologies and control methods have been developed for the PFC application. While the discontinuous conduction mode (DCM) converters such as boost and flyback converters are well suited for low power applicati...

– In recent years it has been observed that some power converters can exhibit deterministic chaos. Since converters have wide industrial applications, it is useful to study their bifurcation phenomena in order to understand the change of behaviors as circuit parameters are varied. Therefore this paper aims to investigate some complex dynamic phenomena that can occur in currentprogrammed DC-DC b...

This paper is a simple and systematic approaches to the design and analysis a pulse width modulation (PWM) based sliding mode controller for buck DC-DC Converters. Various aspects of the design, including the practical problems and the proposed solutions, are detailed. However, these control strategies can't compensate for large load current and input voltage variations. In this paper, a new co...

Cascaded H-bridge multilevel power electronic converters generally require several dc sources. An alternative option is to replace all the separate dc sources feeding the H-bridge cells with capacitors, leaving only one H-bridge cell with a real dc voltage source. This will yield a cost-effective converter. However, the required capacitor voltage balancing is challenging. In this paper, using t...

DC-DC converters are switched power converters. They are used to convert one DC voltage to another DC voltage. It is inordinately used in industry as well as in research. The model of converter system varies from the ON state to the OFF state. The major drawback of the boost converter is the uncontrolled supply of voltage and current. So initially a convectional PID controller is designed to re...

Half-bridge inverter is very suitable for singlephase on-line UPS applications because it offers very desirable features. These include fewer active switches, a common neutral connection – not requiring an isolation transformer, and sinusoidal input currents if a power factor correction (PFC) converter is used at the front end. This paper presents a comparative study of PFC converters for singl...

One of the main orientations in power electronics in the last decade has been the development of switching-mode converters without inductors and transformers. Light weight, small size and high power density are the result of using only switches and capacitors in the power stage of these converters. Thus, they serve as ideal power supplies for mobile electronic systems (e.g. cellular phones, per...

Ac–ac power conversion, the most popular topologies are indirect ac–ac converters with a dc link matrix converters and direct pulse width modulation (PWM) ac–ac converters. The indirect ac–ac converters and matrix converters can provide variable output voltage and variable frequency. However, for applications, where only voltage regulation is needed, the direct PWM ac–ac converters are used to ...

In various kinds of switched-mode power converters, conducted noise due to switching operation frequently causes interference with other electronic equipment. This paper focuses on the common-mode conducted noise generated in switched-mode power converters and presents three examples of noise reduction techniques. First, the common-mode conducted noise is reduced in a common-source type active-...
