Reduced order modeling enables system level simulation of a MEMS piezoelectric energy harvester with a self-supplied SSHI-scheme

摘要

This paper proposes a novel modeling methodology for MEMS-based piezoelectric vibration energy harvesting systems. The approach is based on coupling of the reduced order model and the power circuitry. A numerically accurate reduced order model of the harvester was connected to a synchronized switch harvesting on inductor scheme and optimized subsequently. The harvester output voltage was increased by 17% under open circuit condition.
