Abstract

As technology develops, innovation is increasingly getting significant developments, including in the area of lighting. The development of lamps for street lighting provides innovations, one of which is LED lamps. The buck converter LED a Driver is an option due to its high efficiency, low cost, and small form. The problem is that the Buck Converter has a DC voltage form that has a high ripple. The Buck Converter has a transient output voltage that appears at startup with a high overshoot. The varied source of AC is one of the problems in converter development. There is a potential for improvement in ripple and overshoot with the PWM control technique using Buck Converter. PID is the most widely used choice considering that PID can easily adjust the Buck Converter output accuracy according to parameters. In this research, PID has a Mean Absolute Error (MAE) value of 0.8726, resulting in a setpoint difference of 4.8475% or a difference of 0.8726V. The result of this research show minimal voltage changes in various VAC inputs.

PID控制降压变换器的LED灯驱动器

随着技术的发展，包括照明领域在内的创新也日益取得重大进展。路灯的发展为路灯照明提供了创新，其中之一就是LED灯。降压转换器是一种选择，因为它的高效率，低成本，和小的形式。问题是Buck变换器具有具有高纹波的直流电压形式。Buck变换器具有瞬时输出电压，在启动时出现高超调。交流源的变化是变流器发展中的问题之一。利用Buck变换器的PWM控制技术可以改善纹波和超调。由于PID可以方便地根据参数调整Buck变换器的输出精度，因此PID是应用最广泛的选择。在本研究中，PID的平均绝对误差(Mean Absolute Error, MAE)值为0.8726，因此，其设定点差值为4.8475%，即差值为0.8726 v。本研究的结果表明，各种VAC输入的电压变化最小。
