Next-Generation Three-Phase Inverters: Phase One Annual Report, 1996

Research output: NRELSubcontract Report

Abstract

This report describes the accomplishments of Advanced Energy Systems Inc., under Phase One of their PV Manufacturing Technology (PVMaT) subcontract. These accomplishments include the development of hardware, software, product documentation, and capabilities and specifications for a PV-hybrid three-phase inverter. The document defines models, performance, electrical, and physical systemparameters; enhanced control system, liquid-crystal display interface providing intuitive, multi-lingual operator support; integrated high-precision data and event-logging capability; development of Windows-based system control and data acquisition software for remote monitoring; significant integration and simplification of the inverter control card electronics; enhanced performance of sinewavegeneration that exceeds market requirements for PV-hybrid 'village application' voltage regulation parameters; implementation of digital control core facilitating further development of integrated self-test and diagnostic procedures; compilation of comprehensive Bill of Materials with data sheets for the PV-hybrid product; development of specifications and production ability for magneticcomponents in the inverter; collaboration with WPI Power as a semi-custom manufacturing group; and development of a single-phase test inverter leg for high-power performance and design evaluation.
