i am a final year student of electronics & comm. Engg. . I am looking to work on the project Automatic multilevel car parking. I need your help in this matter.
i wanted to know how the car is automatically placed at the vacant position without driver.
Is it by the use of Rollers in the lift or what ??
please help me in this regard.

Abstract:
This paper presents a generalized cascaded multilevel photovoltaic inverter topology for grid connected PV systems with hybrid phase disposition PWM control scheme. Hybrid PWM strategy based on the combination of fundamental frequency PWM and high frequency phase disposition PWM which reduces the power losses and improves energy efficiency. A digital proportional ....etc

A fast multilevel multipole (FMM) algorithm is derived for the Helmholtz equation and adopted to the symmetric Galerkin boundary element method (BEM) for acoustics. The FMM allows to evaluate a matrix-vector product of the BEM with the computational cost of O(N log 2 N) , thus leading to a significant reduction of computation time and memory requirements compared to standard BEM formulations with computational cost of O(N 2) . This allows the simulation of large scale acoustic models. The performance of the algorithm is demonstrated on the exam ....etc

This paper highlights some effects of an asymmetrical design on three phase multilevel inverters from a supply network point of view. The investigated topology is based on a series connection of single phase inverters (partial cell) in each phase. Each partial cell is fed through a three-phase diode rectifier for a unidirectional power flow, fed itself through the secondary of the power transformer (PT). From analytical relationships in continuous and discontinuous current conduction mode, itâ„¢s shown that a symmetrical multilevel inverte ....etc

Multilevel voltage source converters are emerging as a new breed of power converter options for high-power applications. Here, staircase voltage wave is generated from several levels of dc capacitor voltages. the voltage unbalance between different levels is the major disadvantage of multilevel converters. voltage clamping or capacitor charge control are the main techniques used to solve this. The following types of multilevel voltage source converters are described here:
a)diode-clamp: The diode-clamp method can be applied to highe ....etc
