In recent years, electricity has been a daily necessity for people to help their activities. Along with technological developments, energy demand has increased rapidly. In Indonesia, electric energy is mostly supplied from conventional generators using fossil fuels. One of the impacts of using conventional power generation is air pollution which is caused the global warming. Thus, researchers have developed a renewable energy power generation in the form of a PV system that has no air pollution. PV can generate electricity during the day but often than not can be blocked by bad weather conditions. To solve that problem, a device to optimize the PV output is needed. One of the important components in a PV system is a DC-DC converter. This device can be used as a PV output voltage amplifier and power controller. In this research, PID controller is applied to stabilize the output power of the HVGT (High Voltage Gain Transformerless) topology DC-DC converter. Using the state-space averaging method, a bode plot graph is obtained to determine the stability of the control system of the converter. Similar topologies of DC-DC converter are compared to HVGT topology to know its performance. Simulation and experimental have also been done to validate the theoretical analysis. © 2023 Author(s).
