A power converter with high–efficiency multiple-input power and multiple-output power was designed by using isolated-type flyback structure. In this research, one used solar-cell, house electricity and battery to provide various output power, and charge discharge of battery. While there is enough solar-energy electric power, the system is not only can supply output loads but also can charge the battery at the same time. However, if there is not enough solar energy electric power the battery will supply energy for loads. If battery have insufficient power and there is no solar-energy for input power, house electricity will supply for loads and charge the battery also. In this thesis, one developed a sample electric structure to use renewable energy effectively by single transformer which uses parallel connections of various input supply and have various outputs. Moreover, one used single chips to control input PWM and output feedback of the whole electric circuit to reduce the size and weight of the whole electric circuit.
Key Words : flyback , multi-input, multi-output, renewable energy
