Abstract

DC-DC Boost Converter works to produce an output voltage greater than the input voltage. can be used to supply voltage in various systems. To supply voltage to a system, the boost converter works by applying a switch driven by a PWM generator. This paper presents the design of a control system to adjust the amount of duty cycle on a PWM generator. The use of the LQR control system and integral state feedback to control the duty cycle of the DC-DC Boost Converter is proven to be able to stabilize the output voltage. By providing a frequency of 500 Hz with an input voltage of 1.5 Volts and a reference voltage of 7 Volts, the best performance can be achieved, namely settling time at 5.28 seconds and rise time at 2.6 seconds. The expected performance can be achieved by adjusting the system\'s power supply requirements, such as determining the reference voltage and frequency of PWM generator.

Introduction

Conclusion

DC-DC Boost Converter can work well by controlling the PWM generator duty cycle. The LQR method and integral state feedback are able to stabilize the output voltage of the boost converter and produce a relatively small error. Using the controller, the duty cycle can be set precisely. After the duty cycle controller is used, the next determinant is the frequency used in the PWM generator. By providing a frequency of 500 Hz with an input voltage of 1.5 Volts and a reference voltage of 7 Volts, the best performance can be achieved, namely settling time at 5.28 seconds and rise time at 2.6 seconds.
