N2 - This paper describes a method for maximizing the power delivered to the rectifier in energy harvesters. It is demonstrated that there is an optimal turn-on time for rectifiers to maximize power transfer from the harvester. Next, a maximum power point tracking methodology based on rectifier turn-on time (RTOT-MPPT) is developed for triboelectric energy harvesters. The primary advantage of the proposed approach is the relative independence of the optimal turn-on time on the frequency and peak voltage of the harvester output. Thus, the proposed RTOT-MPPT method reduces the complexity of power tracking and can be efficient for a wider range of harvesters. The method is implemented for a triboelectric harvester and simulated in a 180 n m industrial HV-CMOS process, demonstrating that 34% higher power is delivered to the rectifier in each cycle.
