Abstract
<jats:p>Solar energy, received in the form of radiation (electromagnetic waves), can be converted directly or indirectly into other forms of energy, such as heat and electricity which can be utilized by man .Inverters are the devices usually solid state which change the array DC output to AC suitable voltage, frequency and phase to feed photo voltaic ally generated power into the power grid or local load. Solar energy is time dependent and intermittent energy resources. Inverter may also contain a suitable output step up transformer perhaps some filtering and power factor correction circuits and some power conditioning circuitry to initiate the battery charging and to prevent overcharging. Inverters of PV system based distributed generation (DG) are subjected to wide changes in the inverter input voltage, thus demanding a buck-boost operation of inverters. Further the inverter size, weight and cost is increased. It is designed transformer less inverter that can be operated over a wide dc input voltage range making it suitable for distributed generation applications. Depending on the pulsated DC reference signal the inverter output voltage wave form can varied with respect to the input voltage</jats:p>
