Abstract

Solar energy is one of the renewable energy that has a large potential in Indonesia. Solar energy can be converted into electrical energy using PV. According to the increasing energy demand in Indonesia and the enactment of the feed-in tariff by the government, it will be easier for the sale and purchase of electricity through the on-grid system. This study discusses the design and implementation of a three-phase grid-connected inverter. This three-phase inverter circuit uses sinusoidal pulse width modulation for input signal (SPWM) is used to input the IR2113 circuit a three-phase inverter driver. SPWM used is also a synchronization method to connect the inverter to the grid. Grid synchronization in this study is equating the phase angle and inverter output frequency to the grid. In this design add DC to DC converter type push-pull converter as a three-phase inverter supply and also as a control to adjust the inverter output voltage to fit the grid. The push-pull converter uses an SG3525 PWM IC generator. The circuit can be adjusted according to the voltage you want to produce. The circuit uses a high-frequency transformer as a step up the voltage. The result of the system design is the PV output voltage is increased by the push-pull converter and then to supply three-phase inverter.
