Abstract—A high efficient single stage step up converter is proposed to work as bridgeless circuit for energy harvesting applications. Bridgeless step up converter is an arrangement of boost and buck-boost converter. The proposed topology avoids the complexity of bridge rectifier and efficiently step up the input voltage, reduces the losses and shares the same inductor and capacitor for the operation of both boost as well as buck-boost converter and reduces the size of the converter. The Low AC input voltage of 0.4 v is rectified and boosted to dc output voltage of 3.3 v satisfactorily and the results are achieved with the help of MATLAB software using simulink.
