A resonant converter comprises a first and a second input terminal (1, 2) in order to connect a voltage source (V Bulk ). The first end of a first switch (S 1 ) is connected to the first input terminal (1). The second end of the first switch (S 1 ) is connected to the first end of a second switch (S 2 ). The second end of the second switch (S 2 ) is connected to the second input terminal (2). A first end of a resonant circuit comprising at least one resonant inductance, at least one resonant capacitor (C 1 , C 2 , C s ), and at least a primary winding of a transformer (T 1 , T 1_a , T 1_b ) is connected to the second end of the first switch (S 1 ) and to the first end of the second switch (S 2 ). A third diode (D 3 ) is connected in conduction direction from the first end of the first switch (S 1 ) to the first end of a clamping capacitor (C clamp ). A fourth diode (D 4 ) is connected in conduction direction from the second end of the clamping capacitor (C clamp ) to the second end of the second switch (S 2 ). A comparator (5) is connected to the first and second end of the clamping capacitor (C clamp ). The comparator (5) is connected to a pulse control unit (3) in order to control the first and the second switch (S 1 , S 2 ). |
