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
Energy storage is the capture of energy produced at one time for use at a later time [1] to reduce imbalances between energy demand and energy production. A device that stores energy is generally called an accumulator or battery. Energy comes in multiple forms including radiation, chemical, gravitational potential, electrical potential
An inductor can be used in a buck regulator to function as an output current ripple filter and an energy conversion element. The dual functionality of the inductor can save the cost of using separate elements. But the inductor''s inductance value must be selected to perform both functions optimally.
