The present invention relates to a novel and efficient method for manufacture of toroidal transformers, a first bobbin and a second bobbin for manufacture of toroidal transformers and a system for performing said method for manufacture of toroidal transformers . Said method for manufacture of toroidal transformers has properties superior for automated mass production and comprises the steps of arranging a coil around the periphery of at least one first bobbin of elongated shape and of flexible material, providing at least one second bobbin, said second bobbin being essentially shaped as a circular segment and having at least one first inner cavity and at least one second inner cavity arranged around and along said at least one first inner cavity, feeding said at least one first bobbin, together with said coil, into said at least one second bobbin around said at least one first inner cavity, so that said coil is packed in said at least one second inner cavity, forming a component being essentially shaped as a circular segment, wherein at least one of said component ends defines an opening, joining at least two of said components together, so that a combined component is formed, wherein at least one of said combined component ends defines an opening, and feeding a ribbon of magnetic material through said opening, so that said ribbon is being wound a required amount of tightly packed winding turns inside said at least one first inner cavity until essentially the whole at least one inner cavity of said combined component is filled, said ribbon thereby forming a core . |
