Title: SWITCH-MODE 24-240 VOLT POWER SUPPLY
Abstract:
A flyback switch-mode 24-240 volt power supply comprising a supply voltage capacitor (2), a voltage regulator (3), a transformer (4) which at its output has a voltage stabiliser (5) and finally output condensers (6) where, in parallel to the supply voltage capacitor (2), a circuit (7) is provided that produces a connection in parallel of a capacitor (8) that can be connected via a solid-state switch (9), preferably a MOSFET, that is connected at its base with the output of a comparator (12) that is grounded and connected to a reference voltage such that when the reference voltage exceeds a threshold that corresponds with a supply voltage of less than 50 volts a switch-mode power supply is achieved that ensures correct operation when the supply voltage lies in the range from 24 volts to 50 volts.
