A Single-Inductor Multi-Channel Thermoelectric Energy Harvesting Interface Realizing Uneven Temperature MPPT with 39.6% Efficiency Enhancement and 62mV Tapped-Inductor-Oscillator-Based Start-Up
Abstract
This paper presents a thermoelectric energy harvesting (TEH) interface that realizes: 1) a multi-channel TEH for maximum power point tracking (MPPT) under uneven temperature conditions, improving efficiency by up to 39.6% and 2) a tapped-inductor start-up functionality, which can begin operating at 62 mV with no additional inductors or series switches. The overall design achieves a 90.51% peak end-to-end efficiency.
