Abstract:
1. A switching converter comprising: a first input terminal and a second input terminal, both for connecting to a current source; a first output terminal and a second output terminal, that are both connected to a load; a transformer with a primary winding, a secondary winding and a galvanic isolation between the windings, wherein the primary winding and the secondary winding include two terminals; a primary side first capacitor connected between the first input terminal and the second input terminal; a primary side first inductor with two terminals, connected from its first terminal to the first input terminal; a primary side second inductor with two terminals; a primary side first rectifying device connected between the primary side first inductor second terminal and the primary side second inductor second terminal, thus allowing a flow of current from the primary side first inductor second terminal to the primary side second inductor second terminal; a primary side second rectifying device connected between the primary side first inductor second terminal and the primary side second inductor first terminal, thus allowing a flow of current from the primary side first inductor second terminal to the primary side second inductor first terminal; a primary side second capacitor connected between the second inductor first terminal and the second input terminal; a first switching device connected between the primary side second inductor second terminal and the transformer primary winding first terminal and adapted to be able to set the connection between the primary side second inductor second terminal and the transformer primary winding first terminal to a conducting and a non-conducting state; a second switching device connected between the primary side second inductor second terminal and the transformer primary winding second terminal and adapted to be able to set the connection between the primary side second inductor second terminal and the transformer primary winding second terminal to a conducting and a non-conducting state; a third switching device connected between the transformer primary winding first terminal and second input terminal and adapted to be able to set the connection between the transformer primary winding first terminal and the second input terminal to a conducting and a non-conducting state; a fourth switching device connected between the transformer primary winding second terminal and the second input terminal and adapted to be able to set the connection between the transformer primary winding second terminal and the second input terminal to a conducting and a non-conducting state; a secondary side rectifying means for rectifying a current of the transformer secondary winding; a secondary side filtering means for filtering a current between the rectifier means and a converter output; and means for controlling a voltage between the input terminals.
