In a weak energy environment, the output power of a miniature piezoelectric energy harvester is typically less than 10μW. Due to the weak diode current, the rectifier diode of traditional power management circuit in micro-power energy harvester has a high on-resistance and large power consumption, causing a low charging power. In this paper, an
：. The energy flow between source and the load of micro grid must be balanced to have a constant dc grid voltage. Due to intermittency in the natural sources and the variations in load, energy balance operation demands storage.
