Transformer Configuration in Proteus

Setting up A Transformer in ProteusThe calculation Formula is  L1/L2 = (V1/V2)^2For Example: Design for 6 Volt input ,230volt 50Hz Not considered wattage just for simulation.            Assign L1 = 1H (but 1henry expectable for a 10 or 20 kW transformer)        Then L2 = 1/(230/6)^2                       = 680.5293micro Henrymo...

Development of a DSP-Controlled On-Line UPS

    This research has developed DSP-based digital control techniques for high-performance single-phase on-line UPS systems. A transformerless common-neutral half-bridge AC-DC-AC converter has been adopted for the main power circuit.  All the control functions for an on-line UPS, which includes power-on start-up control, input stage power factor control, battery charging and boosting control, output stage ac voltage regulation, and shut-down control, were realized by using a...
