The present invention relates generally to switched-mode converters of electric power. There are large amounts of switched-mode power supplies used for supplying energy for electrical devices. This brings the need to improve the efficiency of the power conversion. A switched mode converter of the present invention has a secondary winding (L2) in a secondary circuit, which at a first phase both accumulates and releases energy to load (LOAD, C, R), or only accumulates energy. At a second phase the secondary winding (L2) is connected to input voltage and/or releases the accumulated energy in the secondary circuit (L2) in order to increase power release of the primary winding (LI) to the load (LOAD, C, R). The solution increases both the output energy and efficiency of the converter. |
