摘要： Various embodiments include a dimmer for controlling the power consumption of a connectable load. The dimmer includes: two parallel-connected, electrically isolated dimmer channels with control devices; a main control device for the channels; a communication link from the main control device to the channel control devices; and a communication link transmitting information from a first dimmer channel to a second dimmer channel. At least one of the two dimmer channels comprises a measurement device generating information about behavior of the electricity at a location in the measurement dimmer channel. The communication link transmits that information. Starting from the measurement dimmer channel, a channel communication link leads in each case from one dimmer channel to the next dimmer channel. The dimmer determines whether respective times of respective zero crossings of a sinusoidal AC voltage applied to the respective dimmer channel are substantially synchronous.

摘要： Various embodiments may include a dimmer system for controlling the power consumption of a load that can be connected with parallel-connected galvanically isolated dimming channels. The dimmer system may include a plurality of dimming channels, each dimming channel including a sensor for monitoring a temperature of associated switch elements; and a control unit for each dimming channel, the control units 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.
