摘要

提出了一种采用升压变换器的电动汽车功率驱动电路。具有专用电流控制的降压-升压转换器允许实现直流电机的电子齿轮。有了这种拓扑结构，就有可能获得类似于齿轮变速手动变速器所获得的扭矩-速度分布，但以连续的方式，这意味着在高速行驶时功率值有限，但在启动和爬坡过程中扭矩会提高。

Constant power electronic gear for electrical vehicle

This paper presents a power drive circuit for electric vehicles with a buck-boost power converter. The buck-boost converter with a dedicated current control allows achieving an electronic gear for DC motors. With this topology is possible to allow a torque-speed profile that resembles the obtained by a geared manual one but in a continuous manner, meaning that the power value is limited at high speeds but the torque is raised during starting and climbing.
