Abstract
A circuit for controlling a DC voltage source current includes a low-voltage DC bus capacitor, a first set of power electronics half-bridge units, a first set of branch circuit inductors, and a first set of DC switches. All of the first set of power electronics half-bridge units are connected in parallel between a positive pole and a negative pole of a low-voltage DC bus and are also connected in parallel with the low-voltage DC bus capacitor, an output neutral point of each power electronics half-bridge unit is connected in series with one of the first set of branch circuit inductors and one of the first set of DC switches to form one of a first set of current-sharing branch circuits, and each power electronics half-bridge unit and the corresponding current-sharing branch circuit are used to be connected with a DC voltage source to form a DC voltage source branch circuit.
