Document Type and Number:
WIPO Patent Application WO/2017/073829
Kind Code:
A1
Abstract:
The present invention relates to a bidirectional non-isolated DC-DC converter having improved stability. The bidirectional non-isolated DC-DC converter according to one embodiment of the present invention comprises: a DC-DC converter unit including a high-voltage switch and a low-voltage switch, which are a pair of switching elements for switching to a boost mode or a buck mode in response to a switching signal, and an inductor connected to the high-voltage switch and the low-voltage switch; a first protection switch disposed between the inductor and the high-voltage switch of the DC-DC converter unit so as to perform a back-to-back switch function with the high-voltage switch; and a second protection switch disposed between the low-voltage switch and a node formed on a line between the first protection switch and the high-voltage switch so as to perform the back-to-back switch function with the low-voltage switch.
