Performance and Techno-Economic Evaluation of a Three-Phase, 50-kW SiC-Based PV Inverter

Abstract

Department of Energy (DOE) reports produced after 1991 and a growing number of pre-1991 documents are available free via www.OSTI.gov.

Optimal Sizing and Control of a PV-EV-BES Charging System Including Primary Frequency Control and Component Degradation

“…, where X indicates the converter. In this study the converter performance is assumed to be constant over a 15 a lifetime T li f e [46]. Therefore, the total PV and converter investment costs are denoted using (2).…”

Projected Cost of Gallium Oxide Wafers from Edge-Defined Film-Fed Crystal Growth

“…35−40 For instance, the use of SiC increases the manufacturing price of a photovoltaic (PV) inverter; however, the improvements in performance ultimately result in a lower cost of energy generation. 39 Additionally, SiC power modules are more expensive than Si-based modules; however, the SiC enabled design enhancements render the manufactured cost of medium-voltage variable-frequency motor drives on par with their Si counterparts. 40 These are excellent examples demonstrating how TEA can analytically quantify scale-up potential.…”

“…In both examples, the upstream cost was higher than the state-of-the-art, but TEA was able to demonstrate the final energy technology product still had favorable economics. 39,40 TEA can also be used upstream at the manufacturing level to demonstrate the potential for a technology to be transformative. It has been used extensively in understanding Si PV manufacturing to identify critical innovation areas and outline routes that allow Si PV to meet cost targets.…”

“…The importance of techno-economic analysis (TEA) becomes clear when considering the scale-up of technologies for commercial electronics. Economic viability is a large driving factor for the adoption of electronics and energy generation technologies. − For instance, the use of SiC increases the manufacturing price of a photovoltaic (PV) inverter; however, the improvements in performance ultimately result in a lower cost of energy generation . Additionally, SiC power modules are more expensive than Si-based modules; however, the SiC enabled design enhancements render the manufactured cost of medium-voltage variable-frequency motor drives on par with their Si counterparts .…”

Cost analysis of distributed storage in AC and DC microgrids

“…The power converter cost-breakdown model in this study is based on the National Renewable Energy Laboratory (NREL) Inverter model [60]. The NREL Inverter model specifies how to determine the appropriate cost breakdown between materials, manufacturing, selling general and This work derives the material costs of each converter relative to that of the AC-BiD converter.…”
