The easy installation of the solar energy system, no need for fuel, low maintenance and operation requirements, makes it the preferred choice to solve the problem of power outage especially in the day of the summer season. The downside of the solar energy systems is decreasing the generated energy with the rising in temperatures, perfect and simple design of the solar energy system makes it durable over a wide range of temperature increases. This research presents the design of 3-ph (380V, 39A) stand –alone solar system at latitude 32.5 with a high quality voltage and current even when the temperature reaches to maximum levels. The power system of the project contains: 60 PV modules of a half cut cell to reduce the losses in connection lines, and two Mn-Zn toroid core ferrite transformers to transition the solar energy to the inverter with appropriate voltage efficiently. Control system is implemented based on PI controllers for switching function at a certain values of a modulation index parameter (m). The system is modeled and simulated in MATLAM/Simulink, simulation results demonstrate that the rated voltage and current have been obtained with minimum values of Total Harmonics Distortion (THD) and modulation index parameter less than 1.

“…Based on the identification results of the problems above, the problems that must be fixed in this study are the lack of cutting modes and the lack of power regulation and selection. Then the author will design electrosurgery unit monopolar (coagulation) with the addition of Blend mode 3 with the power selection displayed to the LCD character and change the system to Arduino with a frequency of 250kHz In accordance with standard electrosurgery units with a frequency of more than 100kHz [19] and using an inverter to increase the output power [20] The main parts and materials use ic 4093, transistor, transformer, and MOSFeet [21] [22] [23] [24]. By making an Electrosurgery unit with the addition of modes and power selection, it is hoped that it can avoid unnecessary tissue damage.…”

In using the Electrosurgery unit, improper power settings and modes can cause tissue damage, so it is necessary to adjust the cutting mode and power settings needed. The purpose of this research is to design power control and cutting mode in Electrosurgery using Arduino nano as a regulator of power and pulse or duty cycle. The contribution of this research is the creation of power control and mode in the Electrosurgery unit to increase power and cutting mode. This is to control the electrosurgery power. The LM2907 IC frequency to voltage circuit is used as a voltage regulator, which is issued according to the frequency with the power selection LOW, MEDIUM, HIGH. The method used is the CMOS 4069 device as a frequency generator at 250 kHz, then the driver pulse is passed and controlled by the ATmega328 IC, then forwarded to an inverter circuit that functions to increase the voltage and output in the form of power. After the measurement process is carried out on the inverter input with a Blend mode three value, the voltage value is obtained at the low setting 100 V error 0.03%, medium setting 110V error 0.02%, High setting 120 V Error -0.02%. While the measurement results in the coagulation mode are the low setting error of 100 V 0.05%, the medium setting error is 110V 0.08%. High setting error is 130 V 0.003%. The measurements show that the error in power management is lower than 1%. The results of this study can be implemented in the electrosurgery unit to reduce tissue damage due to a lack of cutting modes and power management.
