Claim of US Patent No. 11,032,883

1. A dimmer system for controlling the power consumption of a load that can be connected with parallel-connected galvanically isolated dimming channels, the system comprising:a plurality of dimming channels, each dimming channel including a sensor for monitoring a temperature of associated switch elements; and
wherein each dimming channel comprises an associated control unit, wherein each control unit is configured to shift a respective dimming edge based at least in part on the temperature to distribute power dissipation of the connected load substantially equally across the plurality of dimming channels,
wherein a first control unit within a first dimming channel is further configured to shift the respective dimming edge of the first dimming channel forward or backward in time based at least in part on the temperature of the associated switch elements.
