Research on Maximum Power Detection Algorithm for Automotive Exhaust Thermal Power Generation System
In the automotive exhaust thermoelectric power generation system,due to the high detection error rate of traditional maximum power detection algorithms,a maximum power detection algorithm based on auto-motive exhaust thermoelectric power generation system is studied.Establish a mathematical model for tempera-ture difference thermoelectric power generation in automobile exhaust,obtain the steady-state power generation situation of a single thermocouple with temperature difference,and calculate the maximum output efficiency;Ad-just the voltage of the test point in the circuit,add disturbance to the output voltage or current for regulation,and use interference observation method and two interpolation fitting algorithm to calculate the voltage value of the maximum power point to achieve maximum tracking detection of the automotive exhaust thermoelectric pow-er generation system.The experimental results show that the maximum power detection error rate using the method proposed in this paper is the lowest,improving the tracking accuracy of the maximum power point,and achieving efficient detection of the maximum power of the automotive exhaust thermoelectric power generation system.
