Gridform Inverter Tests and Assessment
نویسندگان
چکیده
An inverter-battery system manufactured by Sustainable Automation Inc. (Sec. 3) underwent testing at the Alaska Center for Energy and Power's Power Systems Integration Laboratory (Sec. 2). The aim of the tests was to demonstrate that inverter-battery systems are a viable strategy for diesel-off mode operation of wind-diesel grids, and to investigate whether this particular inverter-battery system is ready to be deployed in rural Alaska. The system tests showed that diesel-off mode is attainable with the grid-forming inverter tested here (GRIDFORM inverter by Sustainable Automation Inc.). The GRIDFORM inverter provided high quality power and grid stability in diesel-off operation. However, the tests and the design review also revealed several shortcomings of the equipment. It is recommended that these shortcomings be addressed before the GRIDFORM inverter-battery system is deployed to rural Alaska. In addition, the need for extensive operator training with these new technologies is significant and should be factored into a purchase decision.

“The CMOS Inverter” as a comparator in ADC designs
-This paper introduces a single-ended non-offsetcancelled flash ADC architecture, the "Threshold Inverter Quantizer" (TIQ). The TIQ is based on a CMOS inverter cell, in which the voltage transfer characteristics (VTC) are changed by systematic transistor sizing. As a result, a significant improvement of speed and reduction of area and power consumption is achieved.
