Title:
DC-DC CONVERTER
Document Type and Number:
WIPO Patent Application WO/2019/017109
Kind Code:
A1
Abstract:
In a DC-DC converter according to the present invention, a ripple current flowing in an inductor is reduced while still suppressing the addition of component parts or an increase in the size thereof. One aspect of the present invention is a DC-DC converter (1) that obtains an output voltage by increasing an input voltage (VG1). Said DC-DC converter (1) is provided with: a plurality of switching elements (Q11-Q14) for controlling the output voltage; and an inductor (L1) connected to a second node (N12). Each switching element of the plurality of switching elements (Q11-Q14) is controlled into a first state in which electrical conduction between a first node (N11) on the low potential side and the second node (N12) on the high potential side is allowed, or into a second state in which electrical conduction between the first node (N11) and the second node (N12) is not allowed. The plurality of switching elements (Q11-Q14) are connected in parallel between the first node (N11) and the second node (N12).
