摘要： An output voltage rising slope control technique for a power converter is addressed. The output voltage rising slope control technique according to the present invention basically uses a reference voltage generator to precipitate the rising slopes of multiple output voltages of a power converter to become mutually unanimous with each other during start-up period, and thereby avoid the occurrence of system faults in the power converter due to the instantaneously rapid increase of output voltage thereof during start-up period.
