Power Point

To improve conversion efficiency and output quality of the energy harvester, a novel interface circuit with composite maximum power point tracking (MPPT) in energy harvesting applications is proposed in this paper. By using the ultra-low-voltage multiplier with digital control and simple one-cycle variable frequency technique, the converter realizes fast power tracking and high conversion efficiency, and minimizes the power consumption and harmonics, thereby obtaining high tracking precise and low total harmonic distortion (THD). Implemented in 65-nm CMOS process, this converter achieves 85.9% peak power efficiency with dc output voltage of 1.6[Formula: see text]V. The peak tracking efficiency and THD are 99.2% and 1.3%, respectively. The peak output power is 18.31[Formula: see text][Formula: see text]W, and the power loss of the entire converter is only 16.53[Formula: see text][Formula: see text]W.

Piezoelectric Vibration

This paper presents the modeling of a full-wave rectifier circuit based on piezoelectric vibration transducer for energy-harvester system. Piezoelectric vibration crystals are a viable means of harvesting energy for low-power embedded systems e.g. wireless sensor network. Distinct power handling circuits are assessed with the presence of piezoelectric vibration based energy harvesting transducer. Inside the interface circuit, the voltage should be started up when the AC input voltage is very low to supply a regulated DC voltage up to 2V. An active technique is chosen to design an ultra-low power circuit from a piezoelectric vibration transducer. MOSFET bride ac–dc rectifier, energy storage device e.g. capacitor and boost converter with regulator are the common components of the energy harvesting circuits. An integrated promoter ac-dc rectifier circuit and boost converter that accept a maximum input voltage of 0.3V and provide a regulated output voltage of 2V serve as the supply. The MOSFET and thyristor are considered to develop the proposed circuit replacing conventional ac-dc rectifier due to low input voltage at which diode does not work.
