ELECTRICAL POWER SUPPLY SYSTEM AND METHOD OF CONTROLLING ELECTRICAL POWER SUPPLY SYSTEM

Abstract: in an electrical power supply system, when a terminal voltage of a first electrical power storage device is higher than that of a second electrical power storage device, an electrical power generating device and a first load device are electrically disconnected, and the electrical power generating device and the first electrical power storage device are electrically disconnected, thereby charging a smoothing capacitor of the first load device by the electrical power supplied from the first electrical power storage device, and the electrical power generating device and a second load device are electrically connected, and the electrical power generating device and the second electrical power storage device are electrically connected, thereby charging a smoothing capacitor of the electrical power generating device and a smoothing capacitor of the second load device by the electrical power supplied from the second electrical power storage device.
