Minimization of No-Load Power in AC/DC adapter

Now a days usage of electronic equipments
have been increased, in most of these equipments have
energy storage system. To store energy in the battery
with a specified limit of power, certain switched power
conversion circuits are needed. This conversion circuit
delivers power even though the load is detached from the
source. As our country's power demand is very high, the
no load power minimization techniques has to be
developed. A simple ACIDC adapter is proposed in this
Paper. Conventional ACIDC adapters consume
considerable amount of no load power . In proposed
work, the power will get turned off in the source side
itself when the load (i.e the battery) is removed from the
system. By simulation results, the no load power is
minimized to less than O.5mW were the conventional
system has standby power consumption of several
lOOmW. To verify the proposed adapter the simulation
and modelling are proposed in MATLAB.
