ABSTRACT TOUCH SCREEN First computers became more visual, then they took a step further to understand vocal commands and now they have gone a step further and became ‘TOUCHY’, that is skin to screen. A touchscreen is an easy to use input device that allows users to control PC software and DVD video by touching [...]

A novel dead-time elimination method is presented in this paper for voltage source inverters. This method is based on decomposing of a generic phase-leg into two basic switching cells, which are configured with a controllable switch in series with an uncontrollable diode. Therefore, dead-time is not needed. In comparison to using expensive current sensors, this [...]

A Static Synchronous Generator (SSG) is defined by IEEE as a self-commutated switching power converter supplied from from an [...]
