一种自感知型电感同步开关能量采集电路
A Novel Self ̄Sensing Synchronized Switch Harvesting on Inductor
摘要
Abstract
It has been proved that by applying the SSHI ( Synchronized Switch Harvesting on Inductor ) can greatly improve the piezoelectric vibration energy harvesting efficiency. However,additional sensor and controller is needed to control the switch in the SSHI circuit. To reduce the dependence on external equipments,a new circuit called SS-SSHI(Self-Sensing Synchronized Switch Harvesting on Inductor) is proposed. It can achieve the switch-on-off of SSHI automatically through analog circuit without any external testing and control equipment. This paper elaborates the principles of SS-SSHI,analysis the work status and output power of SS-SSHI. Both theoretical and experimental results show that the harvested power can be significantly increased with SS-SSHI circuit,and the maximum power-output increased 99.23% compared to the SEH( Standard Energy Harvesting) circuit.关键词
