STEP-UP DEVICE AND CONVERTER DEVICE

摘要

A booster device (22) includes a shunt resistor (31) with one end thereof being connected to a common bus (51) on a low potential side and a plurality of booster circuits (32-1 to 32-m) that are connected to one another in parallel and are connected between the other end of the shunt resistor (31) and an input bus (52) on a high potential side. The booster device (22) can suppress its cost and mounting area.
