The speed of calculations and the storage capacity do no more represent a problem. Interface becomes more and more friendly, the library becomes larger and the facilities for creating own models are simpler to use. Later on, from this initial program were developed several versions, such as MicroTrans, EMTP-RV, ATP (Alternative Transients Program), PSCAD ( Chuco, 2005 DeCarlo & Lin, 2001).Ĭomparing some of the main simulation programs is not very conclusive, because each one of them are used in some versions trying to solve a large group of problems ( Iordache & Mandache, 2004 Istrate et al., 2009). Electromagnetic Transient Program (EMTP) was bought by Bonneville Power Administration (USA) ( Dommel, 1995). One of the first of them, dedicated to electro energetic systems, was initiated by H.W.Dommel. There are available a lot of simulation programs for transients. Numerical simulation can solve properly such a problem The MP2891 is available in a QFN-56 (7mmx7mm) package.The analysis of transient regimes in electric networks is a complex problem due to great number of elements, some nonlinear, as well as, due to the nonsinusoidal variation of currents and voltages. With only one power loop control method for both steady state and load transient, the power loop compensation is simple to configure. The MP2891 is based on a unique, digital, multi-phase, nonlinear control to provide a fast transient response to the load transient with minimal output capacitors. The MP2891 can monitor and report the output current (I OUT) by sensing the current-sense output of Intelli-Phase TM devices. Device configurations and fault parameters can be easily configured or monitored. The MP2891 stores and restores device configurations. The MP2891 can be configured for up to a maximum of 16 phases on rail 1, and a maximum of 8 phases on rail 2. The MP2891 can work with MPS’s Intelli-Phase TM products to complete the multi-phase voltage regulator (VR) solution with minimal external components. The MP2891 is a dual-rail, digital, multi-phase controller that provides power for NVIDIA PWMVID core power.
