| dc.description.abstract | This study presents a DC-DC boost converter using a Proportional-Integral (PI)
controller for efficient voltage regulation where a 60 V input was utilized to
obtain a stable 110 V output with fast response, low ripple, and high stability
under load variations. The numerical calculation was carried out by employing
MATLAB/Simulink with continuous conduction mode (CCM) approach where
the values of the fundamental components including the inductor, capacitor, and
load resistor were considered based on a 400 W design specification. The PI
controller was tuned using the Simulink PID tuner to optimize system
performance where final tuned gains, Kp=0.023954 and Ki=8.2609 delivered
excellent dynamic results with a rise time of 0.0459 s, a settling time of 0.0746 s,
and an overshoot of only 0.361%. The steady state duty cycle reached 0.46,
matching theoretical expectations. Moreover, the output voltage ripple was
maintained within 0.1%, and inductor current remained steady around 6.85 A,
confirming operation in CCM. Error-based performance metrics, including IAE,
ISE, ITAE, MAE, and MSE all showed negligible values, indicating high
control accuracy. | en_US |
