US Patent 7841928 Multi-channel poultry stunner with current sharing feature

A multi-channel poultry stunner with current sharing feature comprises at least two electrodes connected to at least one poultry and a current sharing circuit connected to the electrodes and a stunning voltage. The current sharing circuit generates at least four sets of dither voltages applied onto the poultry via the electrodes. The poultry is stunned by a stunning current generated on the poultry by the dither voltages and the stunning voltage. The advantages of small size and light weight can be accomplished, and very good conversion efficiency can be achieved. Moreover, a stunning current with current sharing feature can be produced to enhance poultry carcass quality.
