Chapter:-1 Introduction This cascaded multilevel inverter has use can be as H-bridge inverters‚ which can connected in series to provide a sinusoidal output voltage. The H-bridge and the output voltage generated by multilevel inverter is the sum of all the voltages generated by each cell. In single phase inverter‚ each phase is connected to single dc source. The multilevel inverter will be in ON stage and when two switches with the opposite positions and direction will remain ON condition.

Student Council speech Good morning my friends‚ my comrades. Exactly a year and five days ago‚ I stood behind this podium speaking to all of you‚ as a stranger‚ but on this day‚ I stand behind this podium not as a stranger but as a familiar classmate and representative. As for the few who do not know me well‚ I’m Ray Liu‚ a dedicated‚ confident and the mad scientist of last year’s student council. In the past year‚ I have helped the student council organize and set up many different activities

1. INTRODUCTION The automatic meter reading(AMR) system as become a necessity for most suppliers as deregulation‚ free customer choice and open market competition occur in the energy supply sector. Power line communication has many new service possibilities on the data transferring via power lines without use extra cables. AMR is a very important application in these possibilities due to every user connected each other via modems using power lines. AMR is a technique to facilitate remote readings

The technologies available are wireless transmission techniques. Induction is an electric toothbrush’s base and handle contain coils which allow the battery to recharge. The electrical transformer has simple action and instance of wireless energy transfer. The primary circuit and secondary circuit of a transformer are not directly connected. The energy transfer takes place by electromagnetic coupling through a process known as mutual induction. An example of this principle is the battery charger
