Synchronized start-up circuit for paralleling operation
Because of hiccup overcurrent protection, when a supply reaches an overcurrent limit, the output voltage will
immediately turn OFF and after a delay turn ON again. In parallel use, all power supplies have to start synchronized
because of the internal hiccup behavior. Otherwise, the supply which has reached overcurrent first will go to hiccup;
this will overload the other supplies, which then will also go to hiccup. When the first supply has recovered from
hiccup (hiccup dead time), the others remain in hiccup. This will immediately drive the first one into hiccup once
again. This means that without a start-up circuit, a system with several power supplies can never recover from an
overload condition or start-up into full load.
The following additional circuit, required to reach synchronized startup, is already implemented inside the
FNR-3-12G and FNR-3-48G shelves.
