PROBLEM TO BE SOLVED: To assure a stable power supply for driving an electrically-driven type supercharger.SOLUTION: This invention relates to a power supply system for an engine with an electrically-driven supercharger comprising: an electrically-driven type supercharger 30 for supercharging intake by an electric motor to a combustion chamber of the engine; a mechanical supercharger T for supercharging to the combustion chamber of the engine under utilization of exhaust energy of the engine; a first power supply device 41 for supplying power for driving the electrically-driven supercharger 30; a second power supply device 42 for supplying electrical power for driving an adjustment valve for adjusting a recovery amount of the exhaust energy of the engine; and regenerative electric power storage means E with a distributing device for distributing the electrical power generated through regenerative power generation at the engine or a vehicle installed with the engine to a first power supply device 41 and a second power supply device 42. The regenerative electric power storage means E comprises a rotating electric machine 20 for performing regenerative power generation through rotation of the engine; and electrical power control means 51 for controlling an amount of regenerative power by the rotating electric machine 20, and the first power source device 41 comprises a battery 41 storing the regenerative electrical power by the rotating electric machine 20 through chemical energy.SELECTED DRAWING: Figure 1

    【課題】電動式過給機を駆動するための安定した電源を確保する。【解決手段】エンジンの燃焼室へ電動機で吸気を過給する電動式過給機30と、エンジンの燃焼室へエンジンの排気エネルギを利用して過給する機械式過給機Tと、電動式過給機30を駆動するための電力を供給する第一の電源装置41と、エンジンの排気エネルギの回収量を調整する調整弁を駆動するための電力を供給する第二の電源装置42と、エンジン又はエンジンを搭載する車両における回生発電で発生した電力を第一の電源装置41及び第二の電源装置42に分配する分配装置を備える回生電力蓄電手段Eとを備える電動式過給機付きエンジンの電源システムとした。回生電力蓄電手段Eは、エンジンの回転によって回生発電する回転電機20と、回転電機20による回生発電量を制御する電力制御手段51とを備え、第一の電源装置41は、回転電機20による回生電力を化学的エネルギにより蓄える蓄電池41を備える。【選択図】図1
