Abstract - Power crisis is being one of the serious topics to
be discussed. There for possible solution for this to provide sufficient amount of power using renewable energy. Among these resources, human population is the only far and away and all weather resource that has not been utilized .we can use proper method required amount of power can be obtain from this resource. We have thought the idea to utilize human walking power to produce electricity and also we have designed a method named foot step power generation platform, when people walk on the platform, electricity is generated in this system uses the pressure due to weight of the person walking on the platform and stored using batteries. For batter result cascade H bridge inverter used. A 5-level threephase cascaded hybrid multilevel inverter that consists of a standard 3-leg (one leg for each phase) and H-bridge in series with each inverter leg with separate DC voltage sources, 24V and 48V. The control signals for this hybrid multilevel inverter are implemented by a using SPWM signal modulated technique and digital technique. Key Words: Renewable energy, Gears, electric power, Cascaded H-Bridge multilevel inverter (CHB), Pulse Width Modulation (PWM).
1.INTRODUCTION Now-a-days electricity has become the basic need of every human being. Electricity is used in each and every place. We cannot live without electricity. Electricity is used in day to day life, industries, transportation, etc. Now to fulfill this increasing demand of electricity, engineers are finding new ways to generate it. There are many places where there is no electricity .so we are generating electrical power by means of renewable energy, by simply walking on the footstep .non-renewable energy is very less so renewable energy is very much in demand now a days. As the availability of conventional energy declines, there is need to find alternate energy sources. All most all the state electricity departments in our country, they are unable to supply the power according to the demand. The power produced by these companies is not even sufficient for domestic utilities; in such critical situation it is very difficult to divert the energy for other public needs. New generation need electricity for each and every small Š 2017, IRJET

appliance they use. Many energy is being wasted and exhausted, like humans bio energy is being wasted, so we can make it possible to use that energy in making a great invention. There by an alternative source must be discovered. Here we going to use renewable energy using footstep is converting mechanical energy into electrical energy. It is clear, safe, and free, does not pollute the environment and thus will be an extremely viable alternative in the days to come. As our population is increasing day by day the pedestrians are moving one after another continuously on the foot paths as well as in the cities, the footstep mechanism generates nonstop energy, which can be stored and utilized to energize the street lights. Here the concept is to convert the mechanical energy in to electric energy. Proposal for the utilization of waste energy of foot power with human locomotion is very much relevant and important for highly populated countries like India and China where the roads, railway stations, bus stands, temples, etc. are all over crowded and millions of people move around the clock. This whole human/bio-energy being wasted if can be made possible for utilization it will be great invention and crowd energy farms will be very useful energy sources in crowded countries. Walking across a "Crowd Farm," floor, then, will be a fun for idle people who can improve their health by exercising in such farms with earning. The electrical energy generated at such farms will be useful for nearby applications. Multilevel inverters have become more attractive for researchers and manufacturers due to their advantages over conventional three-level Pulse Width-modulated (PWM) inverters. They offer improved output waveforms, smaller filter size, lower Electromagnetic Induction (EMI), lower Total Harmonic Distortion (THD) The three common topologies for multilevel inverters are as follows: (1) Diode clamped (neutral clamped), (2) Capacitor clamped (flying capacitors) and (3) Cascaded H-bridge inverter. In addition, several modulation and control strategies have been developed or adopted for multilevel inverters, including the following: Multilevel sinusoidal (PWM), multilevel selective harmonic elimination and space vector modulation. A fivelevel PWM inverter whose output voltage can be represented
