ABSTRACT:
A power supply which automatically configures itself to correctly respond to either a low or a high level of an A.C. supply voltage to supply a single level D.C. output voltage. The supply switches between a voltage doubler and a full wave rectifier operation dependent on the level of the A.C. supply voltage. Once the supply switches to the full wave rectifier configuration, a latch prevents the power supply from switching to the voltage doubler configuration until the A.C. supply voltage is removed from the power supply. The latch prevents damage to components by preventing the power supply from switching to a low input voltage configuration when, in fact, a high input voltage is present.
