A Bridgeless Boost Rectifier for Energy Harvesting Applications

The proposed design compares a single-stage AC?DC power electronic converter to efficiently manage the energy harvested from electromagnetic micro and meso scale generators with low-voltage outputs. This topology combines a boost converter and a buck-boost converter to condition the positive and negative half portions of the input AC voltage, respectively. Only one inductor and capacitor are used in both circuits to reduce the size of the converter. Generally bridge rectifier is very complicated in design structure and also increases the size of converter, it will require a more number of inductor and capacitor, diodes this will increases the power losses. By using this bridgeless rectifier we can step up the input voltage efficiently and also reduces the losses, increases the efficiency of the converter.
