Abstract

See full text

An exemplary elevator drive includes a DC bus. At least some power components in a power section are electrically referenced to the DC bus. At least some control components in a control section including a drive controller and associated inputs are electrically referenced to the DC bus. This eliminates any requirement for isolating the components referenced to the DC bus from each other.
