DESIGNING AND CONSTRUCTING PURE SINE WAVE INVERTER WITH WIRELESS MONITORING

Some remote areas in Indonesia are lack of electrical supply, so renewable energy resources can be an alternative to fulfill the electrical needs. Renewable energy source like wind turbine and solar panel are generating DC (Direct Current) as the output, however most of the electrical devices like television, bulb, fan are powered by AC (alternating current). Pure sine wave inverter has been widely used to convert a Direct Current (DC) into Alternating Current (AC) allowing most DC source from renewable energy source to be converted to meet the requirement of the load with regards to its frequency and amplitude specification of 50Hz 220VRMS. Pure sine wave inverter consists of MOSFET H-Bridge circuit, transformer, filter, and microcontroller. As the result, the output of the inverter will meet the requirement and this thesis is concerned with design, implementation, and test of such inverter.
Keywords: Pure Sine Wave Inverter, Microcontroller, MOSFET, Single Phase
