Abstract
This article presents a dual-frequency (DF) dual-
input–dual-output interface based on a reconfigurable switching
converter for thermoelectric energy harvesting. The DF operation
decouples the rate of energy extraction at the input stage
from the rate of energy distribution at the output stage. The
interface automatically makes transitions among two energy-
harvesting modes and one energy-recycling mode according to
the load condition. The low-frequency harvesting together with
the high-frequency
