I have an energy harvester that generates impulses at frequency as low as 25Hz. Each impulse has a positive and negative parts. The width of each impulse is ~8ms (positive+negative). The PTP amplitude is ~5V. I can use a bridge rectifier but in order to fully rectify the signal I'll need a very large capacitor, something I would like to avoid because of size and weight.
Is there a suitable PM that can handle such an input?
