Hi(adsbygoogle = window.adsbygoogle || []).push({});

My project involves rectification of a voltage produced by a piezoelectric stack subjected to an impact. The voltage shall be rectified using a full wave bridge rectifier.

I aim to use a capacitor (in position of the smoothing capacitor) to store the energy harvested from the impact (simply because the device must fall from a certain height so it cannot be connected to any measuring equipment during its descent). The capacitor shall be disconnected following impact and connected to a volt meter so stored energy can be calculated.

My question is: does anyone have any suggestion as to how I can calculate required capacitor value? I have no idea of the frequency, current or voltage of the piezoelectric stack output, and these are likely to vary for different impacts.

I do know the voltage and current I require from the rectifier output - if that helps!

Any help would be greatly appreciated

Thanks
