Renewable energy technologies are clean sources of energy that have a much lower environmental impact than conventional energy technologies. In the field of renewable energy after boosting operation, for converting DC to AC voltage for feeding load, inverters plays vital role Due to many limitations faced by Conventional voltage source inverter,Z-SourceInverter became popular by preventing the limitations due to its by providing LC impedance network connected between source and load Thereby this inverter can be used for Buck/Boost operation. But presence of LC impedance made the system bulky and not suitable for low power application. This causes the introduction of Switched Boost inverter, which exhibits similar advantages of ZSI with less number of passive elements. This paper proposes closed loop control of switched boost inverter for PV applications with less cost and reduced size. The closed loop control enhances the efficiency of SBI and it also shows fast response to the voltage given as reference. SBI has unique features of buck/boost operation along with AC/DC inversion. This feature is embedded in this topology due to the presence of impedance network in the input side of SBI.
