(GB2342515-A)   NOVELTY - The energy supply circuit has a multi-level controller (W3) providing 3 voltage planes (U1,U2,U3), with respective input/output terminals coupled to 2 different voltage supply paths (Z1,Z2) for HV loads and LV loads and to a back-up energy storage battery (B1), with a variable current distribution between the different input/output terminals.    USE - The energy supply circuit is used for an automobile electrical network supplying a wide range of different electrical loads, e.g. including an electromagnetic valve control and an electrically heated catalyser.    ADVANTAGE - The supply circuit provides a narrow tolerance band for each electrical load for extending its working life.
