Titel
Analog maximum power point of circuit applied to thermogenerators
Abstract
The objective of maximum power point tracking (MPPT) circuits is to find automatically the MPP and therefore extract the maximum amount of power available in the energy supplier (e.g. TEGs, solar cells). Nowadays, the most common techniques of MPPT employ DSPs or microcontrollers. However, simpler solutions employing analog circuits already exist but the power consumption and complexity of these solutions is still not fully optimized. This paper presents a MPPT circuit implemented with four low-power operational amplifiers.
