Photovoltaic Energy: A Circuits and Systems Perspective
The viability of photovoltaic energy has increased tremendously in the last decade as new manufacturing capacity (especially in China) has driven PV module costs to levels never thought possible. However, there remain challenges in achieving true grid-cost-parity for PV compared to other sources such as coal and natural gas. These challenges include balance of system components and system integration costs, both of which are now major focuses of the DOE. This talk will discuss PV systems from a general perspective, targeting audience members who have less exposure to the PV area. The basic configurations of PV systems will be presented from the cell, module, string, array, and power plant level. We will then drill down into the different architectures for the power management system including central inverter, micro-inverter, and other emerging architectures. New classes of multi-level DC-DC converter ‘partial-power processing’ circuits will be presented as next-generation solutions.
Dr. Stauth received his MS and PhD degrees at University of California, Berkeley in 2006 and 2008 respectively. At U.C. Berkeley Dr. Stauth was affiliated with the Berkeley Wireless Research Center (BWRC) and the Power Electronics Research Group, studying under Prof. Seth Sanders. His research focused on high frequency power electronics and RF integrated circuits. In 2008 he co-founded QVSense, Inc. and operated as CTO until QVSense was acquired by Solar Semiconductor. He remained as Director of Hardware Engineering at Solar Semiconductor until 2011. Since 2011 he has been Assistant Professor at Dartmouth College.
