Driver for LED Lamp with Buck Converter Controlled by PID

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.
