Abstract:
1. A converter circuit comprising: first and second input terminals for receiving an input current from a current source; a first capacitor connected between the first and second input terminals; a 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, a midpoint between the series connection forming a first node; a series connection of a first inductive component, a first diode and a second inductive component, the series connection being connected between the second input terminal and the first node, a polarity of the first diode being such that the first diode allows a current to pass from a direction of the second input terminal; a second node formed by a point between the first inductive component and the first diode; a third node formed by a point between the first diode and the second inductive component; a second diode connected between the second node and the first node to allow current to pass from a direction of the second node to the first node; a third capacitor connected between the first input terminal and the third node; second and fourth semiconductor components connected in series and in parallel with the series connection of the first and third semiconductor components; a third inductive component having a first end which is connected to a fourth node formed between the second and fourth semiconductor components, and a second end which produces first output terminal, the first input terminal forming a second output terminal, wherein the first and the third semiconductor components are configured to control a voltage between the first and second input terminals.
