Thermoelectric power generation MPPT method based on non-equal-division multi-division method

摘要: The invention provides a thermoelectric power generation MPPT method based on non-equal-division multi-division method. includes the steps that an actually-measured voltage value of system is selected as independent variable, serves dependent vehicle-exhaust generator module directly connected with electronic load, and values are measured in various working-condition running states engine; subjected to curve fitting obtain polynomial function; function solved multi-point sampling method, taking intervals obtained, large interval divided into multiple small solution intervals; through where maximum located found fromthe after division; then obtained until accuracy meets target requirement; from finally-obtained interval, point approximate generated output system. According speed tracking greatly increased.
