Transformer assembly, and power conversion apparatus and solar power generation apparatus using the same

摘要

In a transformer assembly formed by using a plurality of transformers each formed by winding a primary coil and a secondary coil around a winding core, one terminal and the other terminal of the primary coil are arranged on opposite sides of the winding core, one terminal and the other terminal of the secondary coil are arranged on opposite sides of the winding core, and N transformers in which the coils and the terminals are laid out are arrayed in the lead-out direction of the terminals of the primary coil while M transformers in which the coils and the terminals are laid out are arrayed in the lead-out direction of the terminals of the secondary coil so as to make a line which connects one terminal and the other terminal of the primary coil cross a line which connects one terminal and the other terminal of the secondary coil.
