SWITCH CONTROL CIRCUIT COUPLED INDECTOR BOOST CONVERTER COMPRISING THE SAME AND DRIVING METHOD OF THE COUPLED INDECTOR BOOST CONVERTER

摘要

The present invention relates to a switch control circuit, a coupled-inductor boost converter including the same, and a driving method thereof. A coupled-inductor boost converter includes a first inductor connected between an input voltage and a first contact, a second inductor connected between the first contact and the second contact, and a second inductor connected between the first contact and the ground A power switch, and a switch control circuit. The switch control circuit receives the voltage of the second contact and uses the voltage of the second contact to turn on the power switch at a time point when the voltage of the first contact becomes zero voltage.
