Assignee: JHEECO E-DRIVE AG
Field: Electrical machinery, apparatus, energy (Electrical engineering)
Classification: CPC H  B | IPC B  H

Claim 0:
1. Electrical assembly comprising at least one intermediate circuit discharge unit for intermediate circuit discharge of a multi-level inverter, having a capacitor and a discharge circuit connected in parallel,
where said discharge circuit comprises an active discharge branch with at least one first discharge element and a passive discharge branch with at least one second discharge element,
where said active discharge branch comprises a first control connection and said passive discharge branch comprises a second control connection,
where said active discharge branch is coupled to said passive discharge branch via said first control connection in such a way that said active discharge branch can be controlled by said passive discharge branch,
wherein said electrical assembly comprises a plurality of intermediate circuit discharge units which are arranged as a series circuit,
wherein said electrical assembly is a drive converter for a traction motor of a vehicle with at least three voltage levels, where said intermediate circuit discharge units can be actuated in such a way that the individual voltage levels of said drive converter are adjustable, and
wherein said passive discharge branch comprises at least a first sub-branch and a second sub-branch, where said first sub-branch is formed in connection with said control connection of said active discharge branch and said second sub-branch is formed as a sub-discharge branch.
