    • An electric power system for an automotive vehicle is provided with a generator to which a 48-volt battery, a blower motor and a DC--DC converter are connected in parallel. An output terminal of the converter is connected to a load which is constituted by a 12-volt battery, a head lamp, a vehicle speed sensor and a resistance to which a switch is connected in series. The system is further provided with a voltmeter for detecting a voltage value of the 12-volt battery and an ammeter for detecting a load current applied to the load, a controller for controlling the converter and the switch. The controller controls the converter to start operation and the switch to be turned on when the voltage value detected by the volt-meter is lower than a first predetermined value and the load current detected by the ammeter is smaller that a second predetermined value. Accordingly, an operating period of the converter is shortened and therefore an energy loss generated in the system is suppressed.
    • 一种用于机动车辆的电力系统设置有并联连接有48伏电池,鼓风机电动机和DC-DC转换器的发电机。 转换器的输出端子连接到由12伏电池,头灯,车速传感器和开关串联连接的电阻构成的负载上。 该系统还具有用于检测12伏电池的电压值的电压表和用于检测施加到负载的负载电流的电流表,用于控制转换器和开关的控制器。 当由电压表检测的电压值低于第一预定值并且由电流表检测到的负载电流小于第二预定值时,控制器控制转换器开始操作并将开关打开。 因此,转换器的工作周期缩短,从而抑制了系统中产生的能量损失。
