SOFT START APPARATUS AND CONVERTER APPARATUS USING THEREOF

摘要

PURPOSE: A soft start device and a converter device using the same are provided to stably implement a soft start by operating a driving switch in a linear area when a circuit initially operates. CONSTITUTION: An output part is driven according to an input signal. The input signal follows a frequency variation method. The output part outputs a voltage signal applied to a gate of a drive switch. A control part gradually increases a level of the voltage signal to a predetermined voltage level. The voltage signal linearly increases.
