Abstract
Systems, apparatus, and methods are provided for initializing a voltage bus. An exemplary system includes an input interface, a voltage bus, discharge circuitry coupled to the voltage bus, connection circuitry coupled between the voltage bus and the input interface, and a control module coupled to the connection circuitry and the discharge circuitry. The control module activates the discharge circuitry prior to activating the connection circuitry.
