Circuit for supplying an odd number of parallel or series switched loads with electricity provides equal energy to the loads in series and parallel configurations

摘要

A circuit for supplying an odd number of parallel or series switched loads (R1-3) with electricity comprises controllable switches (31,32,33,4) to switch between parallel and series conditions. The arrangement (S) has means (71,72,73) to ensure an equal energy supply to the loads in either condition.
