Abstract - This paper presents a simple, low cost, and effective technique for hysteresis current regulation to be implemented in three phase PWM grid connected PV inverter. The control method implemented is hysteresis current control, which is easy and robust compared to various literature methods. This obtains a substantial reduction in the magnitude and variation of the switching frequency, subsequently improving. . Therefore, it needs to be connected to the power network via grid-connected inverters using power electronics devices. The power quality of inverter outputs depends much on the control strategy and modulation. Remember to subscribe for videos like this. leave a comment and share the video.
