Abstract

On the basis of studying the maximum power point tracking control strategy, a simulation and experimental model of the tthermoelectric difference power generation system are built to study the actual output power of the thermoelectric difference power generation system under the two control strategies. The results show that the system output under the hybrid constant voltage tracking method & genetic algorithms CVT&GA） is the most stable and the degree of power oscillation is the smallest in the case of significant power oscillation and high pulse voltage. The power generation efficiency of both the constant voltage method and the hybrid CVT&GA algorithm can reach more than 99.2%, and the system output under both control strategies can reach the steady state before 0.1 s.
