A 9-level inverter with a boost converter has been controlled with a fuzzy logic controller and a PID controller for regulating output voltage applications on resistive (R) and inductive (L), capacitance (C). The mathematical model of this system is created according to the fuzzy logic controlling new high multilevel inverter with a boost converter. The DC-DC boost converter and the multi-level inverter are designed and explained, when creating a mathematical model after a linear pulse width modulation (LPWM), it is preferred to operate the boost multi-level inverter. The fuzzy logic control and the PID control are used to manage the LPWM that allows the switches to operate. The fuzzy logic algorithm is presented by giving necessary mathematical equations that have second-degree differential equations for the fuzzy logic controller. After that, the fuzzy logic controller is set up in the 9-level inverter. The proposed model runs on different membership positions of the triangles at the fuzzy logic controller after testing the PID controller. After the output voltage of the converter, the output voltage of the inverter and the output current of the inverter are observed at the MATLAB SIMULINK, the obtained results are analysed and compared. The results show the demanded performance of the inverter and approve the contribution of the fuzzy logic control on multi-level inverter circuits.

Resulting output voltage is not constant due to light intensity and surface temperature of the solar panels. To overcome the output voltage of solar panels that tends to fluctuate, is to add a DC-DC converter to the output side of the DC-DC Converter used in this study is the Quadratic Boost Converter type which has a role to increase the output voltage of the monocrystalline type solar panel so that it remains constant at 24V DC. using Mamdani Fuzzy Logic Control as a method of controlling PWM switching. The results obtained from this study are that the quadratic boost converter can keep the output voltage of the solar panel constant at 24V, with low ripple voltage and overshoot. The Mamdani fuzzy logic method used can produce a constant output voltage value with a rise time of ± 5 seconds. The efficiency obtained from this converter hardware is quite good, ranging from 76% - 88%.

Buck-boost Converter adalah jenis konverter DC-DC yang memiliki magnitudo tegangan keluaran yang lebih besar dari atau kurang dari besarnya tegangan masukan. Ini setara dengan konverter flyback menggunakan induktor tunggal dan bukan transformator.Buck-boost Converter dengan kontroler logika fuzzy menggunakan sinyal Pulse Width Modulation. Dalam penelitian ini, penggunaan panel surya terintegrasi dalam desain buck-boost converter dengan kontrol logika fuzzy sinyal Pulse Width Modulation atau PWM. Mikrokontroler yang mengukur input dan output tegangan dari sistem dan melakukan percobaan dimana ditentukan ketika pembacaan tegangan panel surya lebih dari 14 V sampai maksimal 18 V, mode buck dioperasikan. Ketika pembacaan tegangan panel surya setidaknya 6 V sampai dengan 13 V, mode boost dioperasikan. Dari percobaan yang telah dilakukan, pada saat Output Positif (OP) di-set 35 dan Output Negatif (ON) -20 sistem memasuki rise time pada saat 17 s dan segera memasuki settling time sesuai dengan setpoint.
