Charger Capable of Performing Integrated Control and Separate Control of Parallel Operations
First Claim
1. A charger capable of performing integrated control and separate control of parallel operations, comprising:
- a plurality of charging modules connected in parallel with each other, each charging module comprising;
a rectification unit for converting input AC power into DC power;
a power conversion unit for dropping the power input through the rectification unit by switching the power;
a switching control unit for controlling a switching operation of the power conversion unit;
a DC unit for converting the switched power, input through the power conversion unit, into DC power, and supplying the DC power to a battery;
a detection unit for detecting an output voltage and an output current of the DC unit; and
a computation control unit for receiving the voltage and current, detected by and fed back from the detection unit, computing the voltage and the current, and transmitting a control signal required to allow the DC unit to sequentially supply a primary constant current, a constant voltage, and a secondary constant current to a battery.

Abstract
The present invention relates to a charger capable of performing the integrated control and separate control of parallel operations. The charger includes a plurality of charging modules connected in parallel with each other. Each of the charging modules includes a rectification unit for converting input AC power into DC power. The system also includes a power conversion unit, a switching control unit, a DC unit, a detection unit, and a computation control unit. The computation control unit receives the voltage and current, detected by and fed back from the detection unit, computes the voltage and the current, and transmits a control signal required to allow the DC unit to supply a primary constant current, a constant voltage, and a secondary constant current to a battery.
