A method for operating an electrical circuit, in particular of a converter is described. The circuit, in at least one embodiment, includes a line-side converter that is coupled to a capacitor. The line-side converter includes at least two series connections, each including at least two power semiconductor elements, and each of the at least two series connections being connected parallel to the capacitor. The line-side converter is coupled to an energy supply system. The DC voltage that is present at the capacitor is determined. A maximum voltage is predetermined. If the DC voltage present at the capacitor is determined to be greater than the maximum voltage, then at least two of the power semiconductor elements are switched into their conductive state in such a manner that the capacitor is discharged in the direction of the energy supply system.
A method for operating an electrical circuit including (i) first and second converters and (ii) a capacitor interconnected therebetween, each converter including at least two series connected power semiconductor elements in parallel with the capacitor, the first converter being configured for coupling to an energy supply, the method comprising:
A computer readable storage device having stored thereon instructions which, when executed by a processor, cause the processor to perform a method for operating an electrical circuit including (i) first and second converters and (ii) a capacitor interconnected therebetween, each converter including at least two series connected power semiconductor elements in parallel with the capacitor, the first converter being configured for coupling to an energy supply, the method comprising:
