Parallel Forced Sharing
Two switchmode power supplies with feedback loops will do strange and sometimes unexpected things when connected in parallel. Often one supply will carry the entire load until its current limit is reached. If it starts hiccuping before the other one comes to its rescue the two supplies may start a chaotic oscillation. The answer to this problem is to use power supplies that are made to communicate with each other so they can collaborate, a switchmode power supply feature know as parallel forced sharing. Sometimes this takes the form of a master-slave operation, and sometimes they just force each other to put out the same current.
