ABSTRACT:
In this paper, a main structure of DC distributed power
system is introduced; the stability of the output voltage in parallel system is
put forward. This paper analyses the output impedance of master-slave current
sharing mode and average current sharing, analyses the stability of parallel
system through simulation, there is Right-half plane (RHP) polar in the Bode
plot of input impedance. At last this paper distinguishes whether this system
is stability and verifies the validity of the simulation.
