Design and Implementation of an Isolated Two-Stage Dual Active Bridge Topology Inverter for Solar PV Off-Grid

In this research, an isolated dual active bridge topology inverter with an off-grid system is designed and manufactured. Using an isolated dual active bridge topology inverter, DC voltage is changed into AC voltage. The specific goal of this research is to apply a circuit topology-focused design to create an inverter with good load efficiency and low regulated voltage. Using Arduino Uno and SPWM signal creation, a clean sinusoidal wave is output from the inverter. The average inverter load efficiency in this study is 35%, and the average inverter voltage regulation is 5%, indicating that the inverter has a good ability to maintain the stability of its output waves.
