(DE19832874-A1)   NOVELTY - The condenser (6) is connected across the outputs of two diode arrays. The PSU (1) includes a controlled DC/DC converter (7) connected to the output of a diode array and to the power supply output.    USE - To supply DC power for a system of electromagnetically-controlled engine valves, used in a vehicle.    ADVANTAGE - This PSU costs relatively little, yet is capable of supplying adequate power efficiently, over the entire engine speed range, including during starting. Fuel is saved by use of the DC/DC converter and accumulator in those regions of the generator characteristic, where the generator is less efficient. During normal running it can be switched off, reducing generator flux and eddy current loss.    (JP2000083329-A)   NOVELTY - The condenser (6) is connected across the outputs of two diode arrays.
