We theoretically investigate the behavior of Andreev interferometers with three superconducting electrodes in the current-biased regime. Our analysis allows us to predict a number of interesting features of such devices, such as both hysteretic and nonhysteretic behavior, negative magnetoresistance, and two different sets of singularities of the differential resistance at subgap voltages. In the nonhysteretic regime we find a pronounced voltage modulation with the magnetic flux which can be used for improving the sensitivity of Andreev interferometers.
