  • Active damping circuit for electric chopper circuit
    Patent number: 8604860
    Abstract: A snubber circuit for a chopper circuit has at least one chopper transistor with terminals connected to a first line and to a second line, the first line being at a power supply potential and the second line being at ground potential. The snubber circuit has a capacitive element and a charging diode for charging the capacitive element. The charging diode and the capacitive element are connected in series to each other and together they are connected in parallel with the chopper transistor. The snubber circuit has an inductive element having a first end connected to a connection point situated between the charging diode and the capacitive element, and a second end connected to one of the lines.
