  • Patent number: 10236676
    Abstract: The invention is a pulse-controlled inverter with one or more semiconductor switches and freewheeling diodes arranged in parallel to each semiconductor switch. The semiconductor switches are triggered only when the current does not flow through a freewheeling diode that is arranged in parallel to the semiconductor switch. This allows the number of triggering processes for the semiconductor switch to be reduced. The reduced number of triggering processes for the semiconductor switches results in lower power losses and an increased service life of the entire system.

  • Patent number: 10236874
    Abstract: The invention relates to an overvoltage protection circuit (5) and a method for protecting a power semiconductor (31, 32) from over-voltages. For this purpose, a voltage applied across a power semiconductor switch is first converted to a lower voltage signal corresponding to the voltage applied to the power semiconductor switch by means of a resistance voltage divider. The reduced voltage signal is then evaluated by means of an overvoltage detector, such as a Zener or suppression diode, and the power semiconductor switch to be protected is activated if the response voltage of said diode is exceeded. By lowering the voltage level by means of a voltage divider, a Zener or suppression diode having a lower voltage level can be used for monitoring the overvoltage, said Zener or suppression diode having improved operating properties in comparison with corresponding diodes having a higher voltage level.
