System for providing direct current at various voltages from batteries in series, comprises a continuos/continuous convertor which is connected such as to equalize battery currents during charge and discharge

摘要

Vehicle electrical supplies are taken at 12V and 24V from the terminals (7,8) of a system which has two 12V batteries (1,2) connected in series and charged by an alternator (3). A continuous/continuous push/pull type convertor (4) is connected between the common battery connection and the 12V output terminal (7) and acts to equalize the battery currents while charging and discharging
