Abstract
The invention relates to an electrical circuit arrangement for driving switching power semiconductor components at high voltage potential with a control signal predetermining a switching information for the power semiconductor component and an output voltage directly controlling the power semiconductor component. A non-controllable semiconductor valve is used as component with high dielectric strength for transferring the switching energy and the switching information.
Claims9
An electrical circuit arrangement for driving a switching power semiconductor component at a high voltage potential, the electrical circuit arrangement comprising, a circuit configured to convey a control signal (A) including switching information for the power semiconductor component, the switching information being transferred to an output voltage directly controlling the power semiconductor component, a non-controllable semiconductor gate being used for transferring switching energy, wherein the non-controllable semiconductor gate is constructed as a component with high dielectric strength for transferring the switching information:
- wherein the control signal (A) determines the variation of a second output voltage (Us) of a controllable voltage source which is connected in series with the non-controllable semiconductor gate and polarized in the forward direction, and a capacitor arrangement.
