Summary:
In this study, we analyze the bifurcation phenomena that occur in a power conversion circuit with a thermoelectric module (TEM) connected as a power source and investigate its dynamic behavior. First, we show a simple equivalent circuit model. Next, we derive the Poincar? map, which discretize the inductor current and capacitor voltage at each clock cycle. Then, we calculate the one-parameter bifurcation diagram in the case of TEM based on the simulation results of the Poincar? map. Finally, we compute the one-parameter bifurcation diagram and clarify the qualitative properties of a power conversion circuit with TEM.
