FIELD: electricity.
SUBSTANCE: current (I) on the load switch is continuously detected for synchronisation, the effective value (Ieff) is determined, and this value is differentiated. The corresponding time moment (t2), at which the maximum or minimum of the differentiated value comes in, is estimated as the time moment (tLU) load switch jump and forms a synchronising pulse.
EFFECT: simplifying and increasing the reliability of providing the possibility to determine the operation time of the energy accumulator and making reliable synchronisation.
