Abstract
A system may include a pre-charge stage and a voltage converter. The pre-charge stage may include a controller circuit configured to generate a control voltage and a current regulator electrically coupled to the controller circuit and configured to generate a first voltage, a second voltage, and a third voltage. The voltage converter may include a capacitor, a hold capacitor, and switches. The capacitor may include a first plate and a voltage on the first plate may be equal to the first voltage. The capacitor may include a second plate and a voltage on the second plate may be equal to the second voltage. The hold capacitor may include a plate and a voltage on the plate may be equal to the third voltage. The current regulator may be configured to regulate a current on the switches during accumulation of an initial charge on the capacitor and the hold capacitor.
