<p>Method and apparatus for the charging a battery which as a stand-by supply is connected to the output of a controllable rectifier supplying a load measures the charging current from the rectifier to the battery at certain instants in order to obtain the change of the charging current, the current value at each measuring instant being stored and, after that, the value being compared with the value of any of the previous measuring instants. The result of this comparison is used as a control condition for a controllable rectifier in order to determine the output voltage from the rectifier.</p> |
