Mil is a thousandth of an inch (0.001') which is 25.4 μm '1f' & '1F' doesn't mean '1 farad, instead '1' is correct Older SPICE software doesn't support the µ (Mu) character '1m' & '1M' doesn't mean '1 megaohm, instead '1MEG' is correct Wrong use of m / meg / mil are common mistakes in all SPICE programs Linear Technology Ltspice Xvii Download SPICE In LTspice, any suffix (left column) can replace the decimal point of a real number, a common format for printed schematics. Follow the instructions below to run the demo circuits in LTspice. These demo circuits are designed to ensure proper performance and have been reviewed by Analog Devices’ factory applications group. Selected Analog Devices devices also have demonstration circuits available for free download. LTspice for Windows PC provides macromodels for most of Analog Devices’ switching regulators, linear regulators, amplifiers, as well as a library of devices for general circuit simulation.
LT spice is a powerful, fast and free simulation software, schematic capture and waveform viewer with enhancements and models for improving the simulation of analog circuits. This enhancements to SPICE have made simulating switching regulators extremely fast compared to normal SPICE simulators, allowing the user to view waveforms for most switching regulators in just a few minutes. Included in the download of LTspice are macromodels for a majority of Analog Devices switching regulators, amplifiers, as well as a library of devices for general circuit simulation. Know how to derive an averaged equivalent circuit model and solve for the converter efficiencyĪ basic understanding of electrical circuit analysis is an assumed prerequisite for this course.LTspice is a high performance SPICE simulation program app, schematic capture and waveform viewer with enhancements and models for easing the simulation of analog circuits.
Be able to solve for the steady-state voltages and currents of step-down, step-up, inverting, and other power converters.Understand what a switched-mode converter is and its basic operating principles.Assignments include simulation of a dc-dc converter, analysis of an inverting dc-dc converter, and modeling and efficiency analysis of an electric vehicle system and of a USB power regulator. Principles of converter circuit analysis are introduced, and are developed for finding the steady state voltages, current, and efficiency of power converters. This course introduces the basic concepts of switched-mode converter circuits for controlling and converting electrical power with high efficiency. This course can also be taken for academic credit as ECEA 5700, part of CU Boulder’s Master of Science in Electrical Engineering degree.
