GENERAL DESCRIPTION
The system basically consists of Two Float Cum Boost Chargers. Each Float cum Boost charger is
capable to supply the load and Battery Charging requirements. In normal mode of operation, the
battery assembly is float charged by both the chargers while feeding the DC load thus operating in
parallel and sharing the total load. When FCBC - 1 fails, the other charger FCBC - 2 comes into
operation and supplies the load and battery bank.
Both Chargers basically consists of input transformer, Rectifier Bridge, Filter circuit and Charger
Control Board. The Functional Block Diagram of redundant the system is enclosed in this packagefor reference. The Input Transformer steps down the AC input voltage to required AC level. The
rectifier is built with SCRs, which are connected in full wave, Full controlled configuration. The
Rectifier Bridge converts the stepped down AC into regulated DC. The Filter Circuit eliminates AC
ripple in the DC output. The charger control board provides the gate pulses to SCRs. Voltage and
current feedback circuits provide error signals to the charger control board to achieve voltage
regulation and current limit.
A charger output voltmeter, a charger output Ammeter, AC input Ammeter and AC input voltmeterare provided to measure respective parameters continuously in each charger. Blocking diode is
provided at the output of each charger to prevent reverse flow of current into the charger, which may
damage the filter circuit in the charger when the battery is supplying the load.
A Battery Charge / Discharge Ammeter, Battery Earth Leakage Ammeter and DC Voltmeter with
selector switch are provided to measure respective parameters continuously in Battery Charger
System.
The chargers, FCBC-1 & FCBC-2 are housed in a single cabinet of Folded sheet steel construction.
All Meters, Indicators and important Controls are brought on to the front door.

SYSTEM THEORY OF OPERATION
The system consists of two identical Float cum Boost Chargers, with necessary Interconnection
Circuit and a Battery Bank. Both chargers are identical in nature & works on the same principle.These chargers are rated to meet the requirement of Load and Battery charging current as
specified. For clear understanding of system description, refer the schematic drawing enclosed.
The Float cum Boost chargers - 1 & 2 are connected to the AC input power through (CB 401/501).
The Input transformer (T401/501) steps down the input AC Voltage to the required level and is
connected to the rectifier bridge (SCR 401-406/501-506) through Fast acting Semiconductor Fuses
(FU 401-402/501-502). PC402/502 are capacitive filter Boards that protect the system from surges
and transients at AC Input. The charger control board PC 401/501 provides gate signals to these
SCRs at appropriate timing depending on the output voltage/current feed back. The Rectifier DC
is connected to DC filter (L 401 / 501 and C 402 / 502) which in turn filters out all harmonics and
provide DC voltage with low ripple content as specified. The Blocking diodes (D401/501) prevent
reverse current flow into the charger. The output voltage of Float cum Boost Charger is adjusted
using the potentiometer R 401-402/501-502 respectively.
The shunt SH 401/501 provides current feedback to charger control board (PC 401/501), which
causes the unit to go into current limit, when the load current (charging current) is more than set
value.
The Rectifier DC is connected to DC filter (L 401 & C 402/L 501 & C 502) which in turn filters
out all harmonics and provide DC voltage with low ripple content as specified.
The meter M 401/501 with shunt, SH 401/501 provides the current feedback to the charger
control Board PC 401/501, which causes the unit to go into current limit beyond the set value.
This Characteristics cause the output voltage to go down when the battery is run down, to
maintain a constant level of charging current.
During normal operation, Charger - 1 & 2 supplying load current and float charge the battery. The
current limit interface board (PC 3) connected across Battery shunt terminal, provides Battery
Charging current limit protection, when both chargers are operating in Float mode.
