Abstract: Disclosed are an electric power conversion apparatus and method in an energy harvesting system. In more detail, it is possible to obtain the maximum electric power from the plurality of energy sources by selecting the connection structure between the source terminals or the connection structure between the source terminals and the collection terminals using the electrical characteristic values (for example, open voltage, short current, and internal impedance) of each source and adjusting the load impedance in the selected connection structure in the energy harvesting system.
