<p>The primary circuit (1) includes a current generator which feeds the input terminals (2,3) and the secondary circuit (4) includes a voltage generator connected in parallel with the output terminals (5,6). Alternatively the primary circuit (1) includes a current generator connected in parallel with the input terminals (2,3) and the secondary circuit (4) includes a current generator connected to the output terminals (5,6). Electric energy conversion circuit comprising: (a) N transformers each with primary (PN) and secondary (SN) windings; (b) a primary circuit (1) connected to input terminals (2,3) to which the transformer primary (PN) terminals are connected; (c) a secondary circuit (4) connected to the output terminals (5,6) to which the transformer secondary (SN) terminals are connected. Each primary circuit (1) and secondary circuit (4) of the converter includes a group of switches (IN) (uni-directional, bi-directional, diodes, IGBT, thyristors, triacs, field effect or bipolar transistors, contactors, contacts, or other types) connected to the N primary and secondary windings. A controller (7) controls the switches (IN) of at least one of the primary or secondary switches. The switches (IN) are connected so that they can connect the primary or secondary windings in series or parallel via the controller (7).</p> |
