Abstract

A novel maximum power point tracking (MPPT) algorithm for piezoelectric (PE) energy harvesting system is proposed and implemented. The output voltage of the rectifier, Vrect, is sampled twice during one conversion cycle for MPPT. Through the proposed double-sampling technique, the open-circuit voltage Voc is predicted on the basis of point slope formula, and the power extraction capability from piezoelectric harvesters is improved over the fractional Voc method. This work is implemented in TSMC 0.18-pm process. The maximum power point tracking time is 46 ps and the maximum efficiency is 98.7%. The total active area of the circuit is 1.69 mm2.
