Design and Implementation Unipolar SPWM Full-Bridge Inverter Using Fuzzy Sugeno in DC Microgrid Isolated System

Electricity is a very important requirement for everyday life. Electrical energy needs depend on fossil energy so far, while the availability of fossil energy is dwindling along with increasing electricity demand in the community. To overcome this problem a microgrid system is implemented. The power source of this microgrid system is a DC (Direct Current) power source originating from PV and the battery is then channeled to the DC bus with a voltage that is kept constant at 400 Volts dc by a DC-DC converter. The voltage source coming from the DC bus will be converted to AC (Alternating Current) 220 volts. In an effort to save energy in the system, an inverter is needed that consumes less power in the conversion process and uses methods that can increase efficiency in its use. In this case the unipolar switching technique has high efficiency processes. After the inverter is given an LC filter to make the inverter output into pure sine. Fuzzy Sugeno is used to maintain the inverter output voltage in a dynamic load state.
