Ph.D. students Mr. Morcos Metry and Ms. Minjeong Kim presented their paper titled “A Hill-Climbing Optimization Approach for Closed-Loop Auto-Tuning of the Grid-Connected Ripple-Port Inverters” at the IEEE ECCE-Asia (KEPI ICPE 2019) in Busan South Korea / May 29, 2019.

This paper proposed an auto-tuning closed-loop controller for the ripple port inverter in single-phase photovoltaic micro-inverters. This controller is based on the hill-climbing algorithm and is designed to minimize double frequency ripple on the dc link.
