Abstract
The positive electrode of the unit in an m-th configuration stage (m is an integer satisfying 2≤m≤n) is connected to a negative electrode of the unit in an (m−1)-th configuration stage. A drain-side terminal of the step-up switch included in the m-th configuration stage is connected to a source-side terminal of the step-up switch included in the (m−1)-th configuration stage. A source-side terminal of the step-up switch included in an n-th configuration stage is connected to a negative electrode of the unit included in the n-th configuration stage. The n step-up switches connected in series are connected in parallel to a series circuit including the power storage mechanism and the reactor.
