Abstract
A circuit can be used for charging a capacitor with an AC voltage. In one embodiment, the circuit includes a capacitor coupled to be charged with the AC voltage. An adjustment is configured to adjust a capacitor charge speed according to a value of the AC voltage. The adjustment circuit includes at least one bipolar transistor coupled to receive a voltage at a base of the bipolar transistor. The voltage is a function of the value of the AC voltage.
