Abstract:
In a converter system having an AC/DC converter, and a method for operating a converter system, in which the terminal of the AC/DC converter on the direct-voltage side feeds a series circuit, which has a braking resistor and a controllable switch, the terminal of a DC/AC converter, in particular an inverter, on the direct-voltage side being connected in parallel to the series circuit. The output signal of a voltage-acquisition device is supplied to an evaluation unit, which generates a control signal for the controllable switch. The evaluation unit includes a device for determining the electric power supplied to the braking resistor, in particular from the intermediate circuit, which is determined by the device from the output signal of the voltage-acquisition device, in particular. The output signal of the device is supplied to a controller, in particular a linear controller, and the controller controls its set value toward the output signal of the device. The controller in particular has a linear controller element, in particular a PI controller element or integration element, whose set value, i.e. whose output signal, is forwarded to a difference generator for determining the difference between the set value and the value of the electric power, the set value being supplied, directly or via a limiter, to a parameterizable filter, whose output signal is supplied to a switching element, which in particular generates an output signal for opening or closing the controllable switch as a function of the exceeding or undershooting of a threshold value.

Claim (Index 21):
A method for operating a converter system including a series circuit, having a controllable switch and a braking resistor, connected at a direct voltage-side terminal of an AC/DC converter, and parallel thereto, a direct voltage-side terminal of a DC/AC converter, comprising:\n using a voltage acquired at the terminal of the DC/AC converter and/or the AC/DC converter on the direct voltage-side to determine electric power discharged to the braking resistor when the controllable switch is closed, and when the controllable switch is open, the electric power discharged to the braking resistor vanishes; supplying a time characteristic of the electric power discharged to the braking resistor to a controller to control a set value toward the time characteristic of the electric power discharged to the braking resistor; and supplying the set value of the controller, directly or via a limiter, to a parameterizable filter supplying an output signal to a switching element that controls the controllable switch.
