| Abstract: | In this paper a circuit topology will be proposed for a solar inverter. This solar inverter should be integrated into the back of the solar panel, together with a battery. The maximum power that it needs to produce is 1 kW, with an acceptable efficiency. One of the main constraints is the physical size, which should not be larger than 38x60x4 cm. Furthermore, it should have the capability to work on and off-grid. In order to achieve a suitable design, different circuit topologies are discussed, among which are a topology based on a 50 Hz transformer, a design with a boost converter using an inductor or flyback converter to step up the voltage and lastly a design making use of a high frequency transformer. Component choices in the circuit design are also discussed in order to achieve the best performance for the lowest possible cost. The design of this solar inverter also includes simulations in Matlab Simulink. In the end a solar inverter design based on a high frequency transformer is proposed with a simulated efficiency of 94.5%. |
