An idling scheme of Synchronous Switch Harvesting on Inductor (SSHI) is proposed for piling up output voltage the piezoelectric energy (PE) harvester cycle by cycle, to deal with PE harvester’s low voltage. The rectifier integrates active diodes and a parallel-SSHI technique simple control scheme, therefore has high efficiency. simulation results demonstrate feasibility rectifier, which able extract from ultra-low-voltage harvester.
