Design of DC Accumulator Charging using Backup Accumulator Based on Inverter and Converter Device

Abstract

The charging of DC accumulator that
experiences a lack of electric charge energy, usually
utilizes an AC input power from the PLN network. When
the AC input power from the PLN network is unavailable,
a DC power source is used from the backup DC
accumulator as a substitute. The research objective is to
design an internal DC accumulator charging using a
backup DC accumulator equipment based on inverter
and converter equipment. The charging system will use
input power from the backup DC accumulator to replace
the AC input power from the PLN network. The electric
voltage of the internal DC accumulator that is filled
(charged) is the initial condition of V
DC(Acu.Int.)= 8.76 Volts
until it reaches the normal condition of 12.05 Volts with a
capacity of charging current of 5 Ah (Ampere.hours)
absorbs electrical energy of W(Acu.Int.)
= 16.45 Wh(Watt.hours). The results show that the equipment supply
a DC charger of 13.0 volts and PDC
of 21.32 watts to theinternal DC accumulator. The comparison of W
(Acu.Int.) to PDC produces time charging, t(charging)of 46.29 minutes
