PROBLEM TO BE SOLVED: To provide a drive apparatus capable of adjusting a voltage to be applied to a drive part by two batteries with different voltages, with cost and size reduced as much as possible.SOLUTION: A drive apparatus includes: a first battery; a second battery with a voltage lower than the first battery; a step-down part capable of only stepping down an output voltage of the first battery of step-up and step-down, and for stepping down the output voltage of the first battery; a step-up part capable of only stepping up an output voltage of the second battery, and for stepping up the output voltage of the second battery; a drive part for performing driving with at least either of power supplied from the first battery via the step-down part and power supplied from the second battery via the step-up part; and a control part for controlling the step-down part and the step-up part.SELECTED DRAWING: Figure 6
【課題】コスト及び装置規模をできる限り縮小した、電圧の異なる2つの蓄電器から駆動部に印加する電圧を調整可能な駆動装置を提供すること。【解決手段】駆動装置は、第1蓄電器と、第1蓄電器よりも低電圧の第2蓄電器と、第1蓄電器の出力電圧に対する昇圧と降圧のうち降圧のみ可能であり、かつ、第1蓄電器の出力電圧を降圧する降圧部と、第2蓄電器の出力電圧に対する昇圧と降圧のうち昇圧のみ可能であり、かつ、第2蓄電器の出力電圧を昇圧する昇圧部と、降圧部を介した第1蓄電器から供給される電力及び昇圧部を介した第2蓄電器から供給される電力の少なくとも一方によって駆動する駆動部と、降圧部及び昇圧部を制御する制御部とを含む。【選択図】図6
