Abstract

The main theme of this paper is to present a novel sensorless brushless DC motor (BLDCM) drive without using position and current sensors, filter and center-tap voltage. The techniques for this drives, include initial position detection technique [Y.S. Lai et al., April 2003], loss-reduction PWM technique [Y.S. Lai et al., Oct. 2002], and back-EMF detection technique [Renesas Systems Solutions Asia Pte. Ltd., Sept. 2002]. The initial position detection technique provides initial position detection without using A/D converter, filter, current sensors, and hall sensors as shown in [Y.S. Lai et al., April 2003]. The PWM technique [Y.S. Lai et al., Oct. 2002] significantly reduces the conduction losses by invoking the concept of synchronous rectifier. The back-EMF detection technique offers noise-free back-EMF detection results for commutation control of inverter, while not using any filter and center-tap voltage. Experimental results derived from a DVD spindle BLDCM test system confirm the theoretical analysis.

新型无传感器pwm控制的无刷直流电机驱动器，不使用位置和电流传感器，滤波器和中心分接电压

本文的主题是提出一种新的无传感器无刷直流电动机(BLDCM)驱动，不使用位置和电流传感器，滤波器和中心抽头电压。该驱动器的技术包括初始位置检测技术[Y.S.]赖等，四月2003]，损耗降低PWM技术[Y.S.Lai et al.， 2002年10月]和反电动势检测技术[瑞萨系统解决方案亚洲有限公司，2002年9月]。初始位置检测技术提供初始位置检测，无需使用A/D转换器、滤波器、电流传感器和霍尔传感器，如图[Y.S.]所示Lai et al.， April 2003]。PWM技术[Y.S.Lai et al.， october 2002]通过调用同步整流器的概念，显著降低了导通损耗。反电动势检测技术为逆变器的换相控制提供了无噪声的反电动势检测结果，而不使用任何滤波器和中心抽头电压。DVD主轴无刷直流电机测试系统的实验结果证实了理论分析。
