Abstract
A capacitor pre-charge circuit configured to avoid inrush to a capacitor can include a plurality of components configured to ramp a pre-charge voltage over time up to a voltage maximum such that the a pre-charge voltage-over-time curve is not an asymptote. The plurality of components can be configured to linearly ramp voltage, for example, to the voltage maximum. In certain embodiments, the circuit can include an integrated voltage sense circuit.
