    Abstract: This paper proposes a single phase pulse-width modulated (PMW) voltage source uninterruptible power supply known as an improved standby boost uninterruptible power supply (ISBUPS) which centers on keeping the output voltage of the inverter system of the UPS at constant voltage of 220V AC and ripple free when utility power supply fails.

    Abstract: The result of a preliminary economic evaluation of distributed generation of electricity with a molten carbonate fuel cell (MCFC) in Paraguay is presented in this work. For this purpose, a mathematical model that represents the main technical and economic characteristics involved in the operation of MCFCs was applied. The model is applied in a hori... Show More
