摘要：
An adapter circuit in power supplies utilizes a selective voltage doubler which approximately doubles an input voltage with a low line connector and does not with a high line connector. The selective voltage doubler is coupled to a switcher, which in turn is coupled to a resonant circuit. The resonant circuit is coupled to a first diode and a second diode and a filter. When a low line connector is used, the input voltage is doubled and a one diode drop is used. When a high line connector is used, the input voltage is not doubled and a two diode drop is used.
