The aim of study of this paper is design and implementation of a simple and efficient soft switched Pulse Width Modulation (PWM) for three-phase induction motor drives. Soft-switching techniques have gained popularity in recent times because they offer many advantages over hard-switched Pulse Width Modulated inverters such as higher efficiency, higher power density and better performances. The ...

This thesis presents High frequency Soft Switching DC-DC boost Converter. The circuit consists of a general Boost Converter with an additional resonant circuit which has a switch, inductor, capacitor and a diode.In general Boost Converter circuits have snubber circuits where switching losses are dissipated in external passive resistors; which is known as hard switching. As the switching frequen...

In this paper, an interleaved soft switching boost converter for a Photovoltaic Power Conditioning System (PV-PCS) with high efficiency is proposed. In order to raise the efficiency of the proposed converter, a 2-phase interleaved boost converter integrated with soft switching cells is used. All of the switching devices in the proposed converter achieve zero current switching (ZCS) or zero volt...

An enhanced soft switching technique for an interleaved boost converter has better performance characteristics when compared to conventional boost converter. As IBC operates under soft switching the main devices do not have any additional voltage & current stress on the auxiliary devices are at low level. Where main switches operates out of phase and share the output current while providing sof...

In this paper, based on the switching-cell approach, a generalized steady state analysis for families of soft-switching dc-todc converters will be presented. Complete generalized design equations will also be given. The concept of generalization and step by step procedure for the generalized process are discussed and applied to selected soft-switching families such as ZVS-QRC, ZCSQRC, QSW-CC, Q...

The analysis for a given Soft-Switching DC-DC converter family can be generalized using the switching-cell of that family leading to a number of generalized equations with a Transformation Table. In this paper, the concept of generalization and step by step procedure for the generalized process are discussed and applied to selected soft-switching families such as ZVS-QRC, ZCS-QRC, ZCS-CC QSW,ZV...

A soft-switching topology for high power buck converter is proposed. Zero-current turn-on and zero-voltage turn-off is achieved without auxiliary switches. All active switches in the converter transmit power to the load equally. Converter control is simple despite four active switches. Converter operation is described and DC analysis is carried out. All operation modes are identified. The condi...
