In this work, a transformerless DC/DC converter is presented with dual operating modes buck–boost procedure. As simple structure and continuous input current port, the system acts as common ground between output terminal. One mode, quadratic voltage gain ratio D/(1-D)2, other mode D/(1-D). present study, conduction (CCM), steady-state conditions were assumed to analyze efficiency small-signal m...

In this paper, a non isolated multi-input multi-output dc–dc boost converter is proposed. This converter is used to implant alternative energy sources in electric vehicles. However, advantages of different sources of energy are achievable by the implant energy sources. This converter has many outputs with different voltage levels, which can be interfaced with multilevel inverters. In this conve...

Photovoltaic (P.V.) systems have become an emerging field for power generation by using renewable energy (RE) sources to overcome the usage of conventional combustible fuels and massive release dangerous gases. The efficient operation PV system is vital extracting maximum from source. For this, a point tracking (MPPT) algorithm works with DC–DC converter extract P.V. system. Two main issues may...

this paper presents the method of reducing torque ripple of brushless dc (bldc) motor. the commutation torque ripple is reduced by control of the dc link voltage during the commutation time. the magnitude of voltage and commutation time is estimated by a neural network and optimized with an optimization method named particle swarm optimization (pso) algorithm analysis. the goal of optimization ...
