<p>PURPOSE: To suppress noise of electromagnetic wave accompanying the ON/OFF of transistors and prevent overcharging to a battery by controlling the rate of charging to a battery by driving electronic switching elements built in a generator by drive signals from a computer unit. CONSTITUTION: By driving based on the results of calculations by a computer unit 2 and building transistors Tr controlling a field current 1f built in a generator 1, the output of the generator 1 is controlled by the signals of a small current (about 10mA) from the computer 2, and thus the generation of the noise from the electromagnetic wave can be reduced to a level which can be almost neglected. Thus, filters for preventing the noise by suppressing the noise and other measures become unnecessary, an increased cost can be prevented, moreover, many man-hours can be reduced during the development stage for confirming the effect of noise measures, thereby reducing a great amount of man-hours in overall work.</p> |
