The present disclosure relates to a system and method for detecting occupants, and more specifically, to a system and method for accurately detecting positions of occupants in a building using beacon signals.

System and method for detecting occupants

Provided is a converter system including: a plurality of converter modules connected to one power source in parallel; and a controller for storing mapping information of first parameters corresponding to processing power of the converter modules and second parameters corresponding to the number of converter modules that optimally process the processing power among the converter modules, configuring a value of the first parameter according to a measurement value of power input into the converter modules or power output from the converter modules, calculating a value of the second parameter by substituting the value of the first parameter into the mapping information, selecting the number of converter modules corresponding to the value of the second parameters as active converter modules from the converter modules and processing the processing power by using the active converter modules, and controlling output power of the active converter module to gradually increase or decrease in a transient state where the value of the second parameter is changed.

Converter system using efficient map and method of controlling same

The present disclosure provides a charging system including: at least two charging devices including at least two output units configured to supply connected automobiles with charging power, a first bus electrically connected to the output units and configured to transfer charging power to the output units, and a power processing unit configured to process power, which is supplied from a power source, using a first capacity and supply the first bus with the processed power; and a second bus configured to connect a first bus of a first charging device and a first bus of a second charging device, wherein, when a total capacity of charging power supplied to automobiles connected to the first charging device exceeds the first capacity, a part or all of lacking capacity is supplied via the second bus.
