Multi-electrode ablation systems, methods, and controllers are described. In one example, a multi-electrode ablation system includes a power supply configured to be coupled to a plurality of electrodes and a controller coupled to the power supply. The controller is configured to determine a thermal gain of each electrode of the plurality of electrodes. For each electrode of the plurality of electrodes, the controller sets a power limit based at least in part on said electrode's determined thermal gain. The power limit establishes a maximum power that may be dissipated through said electrode.
