Hybrid Portable Universal Adapter is very
efficient and new technology which has capable of
taking DC and AC input both and can provide constant
DC output. This paper presents renewable energy like
Solar panels as DC source and normal AC (230V RMS)
source. It has controlled circuit incorporated in it to
step down AC voltage without using transformer. This
model can give constant DC output of 5v. This circuit
has parallel converter circuit which converts AC to DC
and DC to DC as well. This adapter can be carried
easily and we can use it to charge our mobile phones or
any power bank
