Abstract
A low-capacity power supply is described in which an input capacitance may be adjusted. In one example, input capacitors may be located between an AC power supply and a rectifier. Additional adjustment capacitors may be located on one or more input lines to the rectifier. The adjustment capacitors may be added in series to at least one of the input capacitors to decrease the input capacitance of the rectifier. In this example, the power provided downstream of the rectifier may be adjusted to increased or reduced as needed. In other examples, additional switches are provided for the input capacitors to selectively add their capacitance to or remove their capacitance from the input of the rectifier.
