摘要:
A photovoltaic (PV) power generation system includes at least one PV collection device (12) configured to generate a direct current (30), and a boost converter (32, 34) which is coupled to the PV collection device and configured to convert the direct current to an alternating current (36). The boost converter includes at least one direct current boost inductor (52). The boost inductor includes an inductor core (152) configured to form at least one closed magnetic circuit, at least one coil, and at least one permanent magnet configured to produce a first magnetic flux within the inductor core that flows in a first direction around the at least one closed magnetic circuit. A method for reducing core size and core loss of the inductor is also provided.
