PROBLEM TO BE SOLVED: To dividedly use a high-capacity capacitor and an intermediate-capacity capacitor for regenerative electric power charging, perform electric power movement between the capacitors by a power supply signal for supplying a load current and a regenerative signal for performing regenerative brake, and utilize regenerative power without wasting by using also a boosting circuit.SOLUTION: A driving power source device of an electric automobile comprises: an ACDC conversion unit; a boosting unit; a secondary battery; a first capacitor for charging and discharging regenerative electric power output from the ACDC conversion unit and boosted by the boosting unit; a second capacitor for charging and discharging regenerative electric power discharged from the first capacitor and boosted by the boosting unit; a pair of first switching elements which are disposed between the ACDC conversion unit and the boosting unit and between the boosting unit and the first capacitor and are turned on when a regenerative signal is input thereto; and a pair of second switching elements which are disposed between the first capacitor and the boosting unit and between the boosting unit and the second capacitor and are turned on when a power supply signal is input thereto.SELECTED DRAWING: Figure 1

    【課題】回生電力充電用の大容量のキャパシタと中容量のキャパシタとを区分使用し、キャパシタ間の電力移動は、負荷電流を供給する給電信号や回生制動を行う回生信号により行い、昇圧回路を兼用して回生電力を余すことなく活用する。【解決手段】ACDC変換部と、昇圧部と、2次電池と、ACDC変換部から出力され、昇圧部で昇圧された回生電力を充放電する第1キャパシタと、第1キャパシタから放電され、昇圧部で昇圧された回生電力を充放電する第2キャパシタと、ACDC変換部と昇圧部との間、及び昇圧部と第1キャパシタとの間に配置され、回生信号が入力するとオン動作する一対の第1スイッチング素子と、第1キャパシタと昇圧部との間、及び昇圧部と第2キャパシタとの間に配置され、給電信号が入力するとオン動作する一対の第2スイッチング素子とを備えた。【選択図】図1
