Claim 0:
1. A heat transfer system, comprising:
an electrocaloric element comprising an electrocaloric material, and electrodes arranged to impart an electric field to the electrocaloric material;
a first thermal flow path between the electrocaloric material and a heat sink;
a second thermal flow path between the electrocaloric material and a heat source; and
an electric power source on operative electrical communication with the electrodes; and
an arc suppression circuit in series with the electrocaloric element, comprising:
an interruptible electrical connection configured to interrupt the electrical connection in response to detection of an arc between the electrodes; and
a series shunt connection in parallel with the interruptible electrical connection, said series shunt connection including a series shunt load;
wherein the interruptible electrical connection comprises: a first interruptible mono-directional connection configured to conduct current in a first direction with respect to the electrocaloric element, and a second interruptible mono-directional connection configured to conduct current in a second direction opposite to the first direction with respect to the electrocaloric element.
