Abstract: A power supply device having variable output voltage includes a controller, and a first power supply module and a second power supply module connected in parallel. The controller selectively outputs a first voltage control signal and a first switch control signal to the first power supply module, or outputs a second voltage control signal and a second switch control signal to the second power supply module according to a voltage requirement signal. An output power of the first power supply module has a first voltage value selected from a first voltage value set, an output power of the second power supply module has a second voltage value selected from a second voltage value set, and a minimum value of the first voltage value set is greater than a maximum value of the second voltage value set. Thus, more extensive voltage output capabilities are provided, and good power conversion efficiency is achieved at the same time.

Abstract: A charging device and a safety function control circuit and method thereof are provided. When a charging device is not connected to a load, a converted voltage value of a power connection terminal of the charging device is kept to be lower than a safe voltage value so as to maintain a safe mode. The safety function control circuit includes a first control module and a second control module for constant voltage control. The first control module and the second control module perform matching control on a power conversion circuit of the charging device, and in case of a single fault of one of the control modules, the other module is still capable of keeping the converted voltage value to be less than the safe voltage value. Thus, it is ensured that the safe mode stays functional in case of a concurrency of both a single hardware fault and a single firmware fault.
