Abstract

We establish an empirical model to project the highest power output from a photovoltaic power converter (PPC). This model helped us achieve over one watt electrical output power from a single fiber channel. A total of 1.2W electrical power output from two parallel connected 8-segment devices was obtained from a well heat-sunk package with 4W laser illumination from a single fiber. To the best of our knowledge, this is the first time that, over one watt electrical power has been delivered by a single fiber channel. Over 30% power conversion efficiency was maintained in this high power conversion process, whereas the power conversion efficiency was over 40% at low laser input power. This high electrical power output enables more applications in sensing, safing, or arming that could not be achieved before due to less available power. It also further strengthens the position of this unique solution of providing isolated power in harsh, noisy and high-voltage environments.
