Title：Piezoelectric Energy Harvesting Power Conditioning Circuits: The History and Future
Venue: 張江校區微電子樓389會議室
Abstract:
the energy harvesting technologies provide a promising power solution for future distributed and mobile electronics. The power conditioning circuits act an important role in the vibration energy harvesting systems. In the piezoelectric energy harvesting (PEH) systems, the development of energy harvesting interface circuit has experienced four generations since the 2000s: the passive rectifiers, synchronized single-switch circuits, doubleswitch circuits, and multi-switch circuits. It gradually arrives at an understanding that the increase of voltage transition numbers helps minimize the energy dissipation in power conditioning. On the other hand, since the third generation, the bidirectional energy transfer was introduced under the alias active energy harvesting, energy injection, energy investment, pre-biasing, etc., towards larger energy extraction. More energy extraction creates more income, while less energy dissipation reduces the expenditure. The synergy of both features has led to a substantial increase of the net harvested energy. This talk briefly reviews the development of four generations of energy harvesting interface circuits. Base on that, we introduce a general idea and some practical implementations towards the cutting-edge PEH interface circuits, in particular, the multilevel bidirectional power conversion circuits. The global view on the historical evolution of the PEH circuits, their synergy with the mechatronic dynamics, and the related applications helps the analysis and prediction towards the future development of piezoelectric power management circuits.
