Resonant frequency tuning of an industrial vibration energy harvester
2014
Journal of Physics, Conference Series
Recently we have reported a new technique for electronic tuning of inertial energy harvesters. An Hbridge power electronic interface is used to apply a variable complex load impedance to the transducer, allowing control over both the transfer of real power to a battery and the mechanical resonant frequency of the system. In this paper we demonstrate the application of this method to two types of resonant inertial harvester designed for marine applications. The first is a pendulum-based device
