摘要

用于无刷直流电机应用的传统降压变换器不满足负载要求，其中包含更多的输出电压波纹和寄生效应。为了克服这种影响，在lo变换器中增加了额外的滤波元件，以消除输出纹波，有效地提高输出电压水平。罗变换器的输出级由电感和电容组成，因此它自然地充当滤波器。输出级存储并向负载传递能量，并使输出电压平滑以产生恒定的输出电压。罗变换器通过改变占空比作为降压和升压变换器。因此，该罗变换器用于所提出的无刷直流电机驱动。滑模控制器用于使系统的速度在短时间内保持恒定。

Improved Speed Control of BLDC Motor using Luo converter By Sliding Mode Control

The classical buck converter for BLDC motor applications do not meet the load requirement containing more ripples on the output voltage and parasitic effects. In order to overcome this effect, the additional filter elements are added in the Luo-converter to eliminate the output ripples and effectively enhance the output voltage level. The output stage of the Luo converter is comprised of an inductor and capacitor so it naturally acts as filter. The output stage stores and delivers energy to the load and smoothens the output voltage to produce a constant output voltage. The Luo Converter acts as both buck and boost converter by varying the duty cycle. Thus this Luo Converter is used for the proposed BLDC Motor Drive. The Sliding Mode Controller is used to make the speed of the System constant in a small amount of time.
