ABSTRACT:
The apparatus comprises first and second input terminals (1, 3) for receiving an input voltage, a number of transformers (7), each of which comprises a primary winding (9) having first (13) and second (15) ends, and a secondary winding (11). At least one end of each primary winding is connected to a switching member (17) which comprises a first controllable switching element (19) and a second controllable switching element (21). This end (15) can be connected, via the first switching element (19), to the first input terminal (1) and, via the second switching element (21), to the second input terminal (3). The switching member (17) may be in a first state or a second state, the first switching element (19) being closed and the second switching element (21) being open in the first state whereas in the second state the first switching element is open and the second switching element is closed. The apparatus also comprises a control unit (31) for cyclically adjusting the various switching members (17) to the first and the second state at different instants.
