Load selection control circuit for current supply, has reference components connected to source to produce limited capacity value, and switch electrically connected with components to allocate capacity value as input of protection circuit

摘要

The circuit has a capacitance protection circuit (20) to which an electrical conversion circuit (10) is connected. A difference circuit (30) has an electrical source (31) to provide reference electricity. Reference components are connected to the source in order to produce a limited capacity value, and a switch (32) is electrically connected with the components to allocate the capacity value as input of the protection circuit.
