Inverter using powerbank as power source with pure sine wave output

Abstract

The current factory-generated inverters, typically use high power sources or energy sources, with a minimum input voltage of 12VDC, 24VDC, 48VDC with an effective voltage output of 220 VAC with a frequency of 50Hz/60Hz. These power sources are usually obtained from starting battery or deep-cycle battery. The problem of inverter currently that portable inverter using a low power source with a sine wave output is not available. So in this research conducted inverter design using power source/ energy source from powerbank 5 VDC 16000 mAh with 50 Hz 40 Vpp sine wave output. Inverter design method in this final project research based on simulation which used LTspice application. And in this inverter system, have been decided to using MOSFET as switching and using h-bridge as inverter topology, because MOSFET has high efficiency compared with BJT or J-FET. This final project research is expected to be an inverter using powerbank resources and become a portable inverter so in the future can be used for loads that require sinusoidal signals such as electric stoves, and can be used also for climbing purposes.
