This paper presents the averaging model of a buck converter derived from the generalized state-space averaging method. The sliding mode control is used to regulate the output voltage of the converter and taken into account in the model. The proposed model requires the fast computational time compared with those of the full topology model. The intensive time-domain simulations via the exact topo...

In this paper, sliding mode control (SMC) for a bidirectional buck/boost DC-DC converter (BDC) with constant frequency in continuous conduction mode (CCM) is discussed. Since the converter is a high-order converter, the reduced-order sliding manifold is exploited. Because of right-half-plan zero (RHPZ) in the converter’s duty ratio to output voltage transfer function, sliding mode current...

In this paper, a DC–DC converter topology with a zero voltage and zero current switching control technique [8] has been proposed for solar PV applications. The proposed converter combine the feature of buck–boost operation capability, at the same time, it can carry out zero voltage and zero current switching on the primary side of the converter transformer. The proposed work has been carried ou...

This study presents a novel Switched Reluctance Motor (SRM) drive system with power factor improvement. Recently, many of the converters with variable speed drives have no input power factor correction circuits. This results in harmonic pollution of the utility supply, which should be avoided. The effect of power factor variation in terms of harmonic content is also analyzed in this study. The ...

A DC-to-DC converter for applications involving a source with widely varying voltage conditions with loads requiring constant voltage from full load down to no load is presented. The switching regulator considered is a Buck converter with Pulse Skipping Modulation control whereby pulses applied to the switch are blocked or released on output voltage crossing a predetermined value. Results of th...

A unified approach is suggested for the derivation of current-tocurrent converter topologies, which relies on duality principles. As conventional duality rules have restricted utility and are difficult to apply with switched mode circuits, special attention is devoted to switch mode converter element dualities. Also, a special means of viewing complex switched mode topologies as a cascade combi...

Finally, the soft switching condition are analyzed, and this article gets the realization of soft switching conditions of the three half bridge DC/DC converter and the influence factors of soft switching conditions of the three half bridge DC/DC converter. Characteristics...

A dc converter is a lossless dc transformer that must supply regulated outputted voltage under varying load and input voltage condition. Also the converter values changes with time, temperature and pressure. Hence to control the output voltage, detailed understanding of the dynamic behaviour, transient response and small signal characteristics of the converter is required, which can’t be unders...
