全方向振动能量收集系统

Collection system of omnidirectional vibration energy

为解决微电子设备的能源供给问题,设计了一种全方向振动能量收集系统。该系统中的振动能量收集装置将外界任意方向的振动能量转化为电能,并通过基于LTC3588-1和LTC4071的能量收集电路,一方面将振动能量收集装置输出的电能转化为稳定的直流电压输出供负载使用,另一方面将剩余的收集能量储存在电池中,当能量不足时通过电池放电给负载供能。仿真结果验证了该系统的有效性和可行性。

In order to solve problem of energy supply for microelectronic device, a collection system of omnidirectional vibration energy was designed. In the system, vibration energy from any direction is converted into electric energy through vibration energy collection device. Then through energy collection circuit based on LTC3588-1 and LTC4071, on one hand, the electric energy is converted into stable DC voltage for load, on the other hand, redundant energy is stored in battery which discharges to the load at the time of energy lack. The simulation results verify effectiveness and feasibility of the system.
