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 package for 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 voltmeter are 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.

13.6& 13.7
As Battery charger designed suitable for VRLA battery, Float and Boost Voltage settings will be designed as per VRLA battery manufacturer Recommended voltage levels Float=2.25V/cell and Boost=2.3V/Cell. Offered charger is designed as its out put voltage shall vary with in the regulation limits, hence pulse limiter zener type is not required.

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.
