【摘要】 现行的蓄电池车辆大多采用直流斩波调速方式,对所用器件要求较高,而且输出谐波较大,引起的损耗也大.本文提出了一种采用新颖技术对蓄电池车辆进行无级调速的方案,使得供给电机的电流平滑,高次谐波小.由于采用自适应调整方式,输出电压连续可调,容易实现平稳起动和无级调速,是现行控制系统的替代产品.更多还原

【Abstract】 : At present,most of the vehicles have their speed regulated by DC-chopper, which has higher requirement to the components and results in larger ripples of the output and greater loss of the energy. The paper presents a new type of stepless speed regulation system for battery powered vehicles,which makes the current supplied to the electric motor smoother than that of the existing DC-chopper. With the self-adeptable regulation mode,the output voltage can be regulated continuously. It is easy to start steadily and realize stepless speed regulation. It is a substitute for the existing control system.更多还原
