ABSTRACT The buck converter functions to control the DC voltage by making the output voltage smaller than the input voltage. The use of buck conveter has problems with the output voltage, so a control system is needed that is able to stabilize the output voltage of the buck converter. The purpose of the thesis is to design and simulate a buck converter DC-DC solar charger system using PID contr…
ABSTRACT Radio over Fiber (RoF) is a system where radio frequency (RF) signals are transmitted through optical fibers to support wireless communication services. The advantage of RoF lies in its lower construction costs and economic feasibility. However, RoF systems face the issue of chromatic dispersion over certain fiber lengths, leading to significant power loss. This research focuses on th…
