ABSTRACT:
A master-slave current distribution circuit for parallel power supplies is disclosed. The master-slave current distribution circuit for parallel power supplies comprising at least a first power supply and a second power supply includes a voltage amplifier, a power converting unit, a current detecting unit, an equivalent diode, an adjustable amplifier, an adding unit, and an energy gap voltage modulating unit, wherein an energy gap voltage formed between the output of the current detecting unit and the non-inverting input of the adjustable amplifier is modulated by the energy gap voltage modulating unit so that an unstability formed from the first power supply and the second power supply under a light load is eliminated.
