摘要：A switch control device, a switch control method, and a converter using thesame are disclosed. The converter includes: a switch; an energy transfer element thatconverts input energy into output energy according to a switching operation of the

switch; and a switch control device that generates a first signal, which is maintained at afirst level during a first interval starting from a first time at which the switch is turned onby using a feedback signal corresponding to the output energy and is then graduallylowered from the first level to the feedback signal during a second interval, and controlsthe switching operation of the switch by using a second signal corresponding to a currentflowing at the switch and the first signal. A malfunction due to an LEC can be effectivelyprevented, and the converter and the converter controller can be implemented to becompact and low-priced.
