Abstract: Exemplary embodiments are directed to a system, method, apparatus, and arrangement for operating a photovoltaic system. The photovoltaic system including a boost converter having a controllable duty ratio, at least two strings of photovoltaic panels supplying an input of the boost converter, wherein the strings are connected in parallel with each other. The system having detector configured to detect a reverse current in any of the strings, and a controller configured to increase, in response to the detection of a reverse current in at least one of the strings, the duty ratio of the boost converter at least until the reverse current stops.

Abstract: A converter circuit includes first and second input terminals, first and second capacitors, the second capacitor having a first terminal connected to the second input terminal and a second terminal forming a positive voltage node, first and third semiconductor components connected in series between the first input terminal and the positive voltage node, the midpoint between the series connection forming a first node, and a series connection of a first inductive component, a diode and a second inductive component. The series connection is connected between the second input terminal and the node. The diode's polarity allows current to pass from the direction of the second input terminal. A second node is formed between the first inductive component and the diode, and a third node is formed between the diode and the second inductive component. A third capacitor is connected between the first input terminal and the third node.
