New resonant rectifier for capacitive sources

A new rectification scheme is proposed for increasing the available output power of electrical generators that have a high output capacitance. The new rectifier could be useful in increasing the output power of piezoelectric generators (PZG) that convert mechanical vibrations to electrical power. The improvement is achieved by a resonant circuit that self commutates the voltage across the output terminals of the PZG, thereby eliminating the shunting of the output current by the output capacitor.
