Abstract
An apparatus includes a power converter configured to provide a constant current charge to a capacitor coupled to a high voltage bus through a mechanical contact, an isolation interface configured to receive a pre-charge signal on a primary side of the isolation interface, and convert the pre-charge signal into a bias voltage signal and a control command signal on a secondary side of the isolation interface, and based on the bias voltage signal and the control command signal, a constant current control unit configured to generate a gate drive signal for the power converter.
