Title:
電気回路、スイッチング電源および燃料電池システム
Document Type and Number:
Japanese Patent JP6660563
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a technique suitable for achieving both of suppression of power loss and suppression of increase in a voltage of a switching element at a high level.SOLUTION: A timing when a second switching element 412 switches from ON to OFF is the same as a timing when a first switching element 411 switches from ON to OFF. A second duty ratio that is a duty ratio of the second switching element 412 is smaller than a first duty ratio that is a duty ratio of the first switching element 411. The second duty ratio is determined in accordance with the first duty ratio.SELECTED DRAWING: Figure 1
