1. A switched power converter unit, comprising:
a DC voltage source (UDC) with a positive output connection (+) and a negative output connection (−); two parallel branches between the positive and the negative output connection of the DC voltage source, each branch comprising a series connection of two switching units (S1, S2, S3, S4); a first output clamp (UA), coupled to a common point (SNA) of the two switching units (S1, S2) of the first parallel branch by means of a first inductive element (L1); coupled to the positive output clamp (+) of the DC voltage source (UDC) by diode (D1), the diode (D1) arranged such to allow current flow from the first output clamp (UA) to the DC voltage source (UDC); coupled to the negative output clamp (−) of the DC voltage source (UDC) by a diode (D2) arranged such to allow current flow from the DC voltage source (UDC) to the first output clamp (UA); a capacitor (C1a) coupled parallel to diode D1, and/or a capacitor (C2a) coupled parallel to diode D2; a second output clamp (UB), coupled to a common point (SNB) of the two switching units (S3, S4) of the second parallel branch by means of a second inductive element (L2); coupled to the positive output clamp (+) of the DC voltage source (UDC) a diode (D3) arranged such to allow current flow from the second output clamp (UB) to the DC voltage source (UDC); coupled to the negative output clamp (−) of the DC voltage source (UDC) by a diode (D4) arranged such to allow current flow from the DC voltage source to the second output clamp (UB); a capacitor (C1b) coupled parallel to diode D3, and/or a capacitor (C2b) coupled parallel to diode D4. |
