The energy harvesting technique has the capability to build autonomous, self-powered electronic systems that does notuddepend on the battery power for driving the low power electronics devices. In this paper, a voltage doubler and bridgelessudboost rectifier power electronic converter is proposed to increase the energy harvesting output voltage from piezoelectricudvibration based transducer. The conventional full-wave diode bridge rectifier and boost converter for energy harvestingudsystem increases significant voltage drop and power losses in the circuit. However, the proposed voltage doubler andudbridgeless boost rectifier circuit reduce the voltage drop and power loses in the circuit and thus increases the efficiencyudof the circuit. The proposed voltage doubler and bridgeless boost rectifier circuit step-up the output voltage up to 3 V DCudfrom an input voltage of 1.9 V AC.
