Matrix converter is basically direct three phase to three phase converter and it’s operation is based upon switching pattern of all nine switches, which are available in this converter. The output of ac converter is fed as the input of three phase induction motor. The performance of three phase matrix converter fed induction motor drive is analyzed by the switching pattern obtained by matrix co...

The power chain of autonomous devices consists of an energy scavenger, power converter and energy storage system. The interaction between a piezoelectric vibration energy scavenger, the power converter and the energy storage system is investigated. A system level approach, including mechanical and electrical domains, is pursued for impedance matching from mechanical domain to electrical domain ...

In this paper, a high voltage gain of DC-DC converter with design and simulation are proposed using coupledinductor. The proposed converter duty ratio is 0.65, so appropriate duty ratio is considering for this design of the converter. Due do more number of switches are considers for the converter circuit will make more switching power losses but in this converter using only two switches and hav...

In this paper an efficient topology of (Single Ended Primary Inductor Converter) SEPIC/Zeta converter is proposed to interface renewable energy sources and the load. The proposed converter is obtained by the integration of the bidirectional converter and the full-bridge converter. As the output voltage of the proposed converter is not reversed this topology provides remarkable advantages than t...

Harmonic pollution and low power factor in power systems caused by power converters have been of great concern. To overcome these problems several converter topologies using advanced semiconductor devices and control schemes have been proposed. This investigation is to identify a low cost, small size, efficient and reliable ac to dc converter to meet the input performance index of UPS. The perf...
