Abstract
A terminal includes an RF-DC conversion circuit outputting DC current by converting AC current received via wireless communication into DC current, a DC-DC converter connected to an output side of RF-DC conversion circuit to convert a voltage of DC current output from RF-DC conversion circuit to a predetermined voltage, and a controller controlling connection and disconnection between RF-DC conversion circuit and DC-DC converter. Controller acquires open circuit voltage Vin_oc on an output side of RF-DC conversion circuit, which is obtained when RF-DC conversion circuit and DC-DC converter are disconnected from each other, and target voltage αVin_oc (0<α<1) obtained by dividing open circuit voltage Vin_oc. When RF-DC conversion circuit and DC-DC converter are connected to each other, controller performs feedback control of DC-DC converter so that an input voltage Vin on a side where DC-DC converter is connected to RF-DC conversion circuit is equal to target voltage αVin_oc.
