Abstract (en)

[origin: WO2010000979A1] The invention relates to a damping circuit for a chopper circuit that comprises at least one chopper transistor (3, y) having terminals connected to a first line (1) and to a second line (2), the first line (1) being at a power potential and the second line (2) being grounded, wherein the damping circuit includes a capacitive member (7) and a charge diode (6) of the capacitive member (7) connected together in series and mounted in parallel relative to the chopper transistor (3, 4), the damping circuit including an inductive member (8) having a first end connected to a connection point located between the charge diode (6) and the capacitive member (7), and a second end connected to one of the lines (1, 2).
