喷个不停gif出处     Programmable switching DC power supply operating mode

 
        The working mode of the power supply can be divided into constant voltage output mode (CV), constant current output mode (CC), series mode, and parallel mode. Among them, in the constant voltage mode, the output current of the power supply changes with the load to ensure a constant output voltage. In the constant current mode, the output voltage of the power supply changes with the load to ensure a constant output current. The output connections of the parallel mode or series mode must be independent, and the output of one power supply can also be connected to the output of another power supply. In order to obtain a larger output voltage, a series mode can be adopted, and in order to obtain a larger output current, a parallel mode can be adopted.
    1) Series mode In series mode, due to the voltage addition (or subtraction), the maximum current is determined by the power supply device with the lowest set value, so the currents of all devices are equal at this time.
    2) Parallel mode In order to increase the total current output, parallel mode can be adopted. At this time, the output voltages of all devices are the same, the size is determined by the power supply device with the lowest rated output voltage, and the total current is the sum of the currents of the parallel branches. If the power supply equipment used has the same specifications, check whether the current distributed on each power supply device is averaged when connected in parallel. Since the current flowing through each power supply device in parallel is the same, if other types of power supply devices are used, there is no overload. Under protective conditions, such voltages may be damaged by current.
