A power supply having one or more power electronic modules that may be replaced without shutting down the power supply. Each power electronic module may be enclosed in a separate compartment of the power supply. Each compartment may have stationary electrical connectors configured to electrically connect to the power electronic module. A racking mechanism connected to a handle outside the compartment may move a power electronic module out of electrical contact with the stationary electrical connectors and/or into electrical contact with the stationary electrical connectors. Movement of a power electronic module within the compartment may occur without shutting down the power supply. Methods of replacing power electronic modules without shutting down the power supply are also provided, as are other aspects.

摘要:
A method for a method for operating a multi-cell power supply having an integrated bypass assembly. According to various embodiments, the method includes detecting a failure in a power cell of the power supply, temporarily placing each of the power cells in a non-conducting state, and determining whether any current is flowing in the failed power cell. The method also includes bypassing the failed power cell after it has been determined that no current is flowing in the failed power cell, and placing the non-failed power cells back in a conducting state.
