In this paper, a controlling system is implemented for a wearable walking supporting device so called as Hybrid Assistive Limb. The control circuit is implemented without considering the biological signals of the human body for the knee part, which is based on the knee joint moment from the human body model. The control and a driving circuit s are implemented to assistive the knee as for the requir ement of knee joint dynamics.


Modeling And Simulation Of Z-Source Inverter, Suresh L Jan 2012

Modeling And Simulation Of Z-Source Inverter, Suresh L

Z – source inverters have been recently proposed as an alternative power conversion concept as they have both voltage buck and boost capabilities. These inverters use a unique impedance network, coupled between the power source and converter circuit, to provide both voltage buck and boost properties, which cannot be achieved with conventional voltage source and current source inverters. To facilitate understanding of Z – source inverter, this paper presents a detailed analysis, showing design of impedance network, implementation of simple Boost control PWM technique and simulation of Z – source inverter for different values of modulation indices.
