Term of the day : 'Parallel'
1) when 2 or more power supply outputs (of the same voltage) are connected together, +ve to +ve and -ve to -ve to increase the total output current (whilst maintaining the output voltage). Care should be taken to ensure that the power supply is suitable for parallel connection as some units will not operate well or may be destroyed by operating in this manner. Additionally, some power supplies need diodes connected in series with their outputs to operate correctly in parallel, check the operation/installation manual for details.
2) The connection of components or circuits in a shunt configuration.
