Voltage Dependent Current Source. The voltage dependent current source consists of two input terminals on the left side and two output terminals on the right side. By inputting a voltage to the input terminal, a current proportional to the input voltage can be output from the output terminal.

Arbitrary Piece-wise linear current source. For times before t1, the current is i1. For times between t1 and t2, the current varies linearly between i1 and i2. There can be any number of time, current points given. For times after the last time, the current is the last current. Syntax: Ixxx n+ n- wavefile=<filename> [chan=<nnn>]

2021年4月2日 · Here a simple and very versatile method of creating a current dependent current source in LTspice is presented. The method makes use of the Arbitrary Behavior Current Source, or “bi” default library component.

#22 #ltspice In this tutorial video I take a look at dependent voltage and current sources in LTspice. I show the various types, how they work, and make a short example with each one. What...

2021年1月6日 · When flagged as a load, the current source starts to deviate from a constant current when the voltage across it drops to 0.5V. The impedance eventually drops to a resistance equal to .25Ω/amp times the value of the current source.

2019年11月7日 · The first syntax specifies a behavioral voltage source and the next is a behavioral current source. For the current source, parallel resistance and capacitance may be specified with the Rpar and Cpar instance parameters.

This circuit element asserts an output current between the nodes n+ and n- that depends on the input voltage between nodes nc+ and nc-. This is a linearly dependent source specified solely by a constant gain.

2019年2月7日 · For an LT Spice simulation I was doing of a transformer, I would like to set the current to 3 amps for a power supply, but I'm not sure how to use a current source for that. I tried putting two current sources to represent the current of a pulsed power source, but the current through the resistor still isn't limited to 3 amps.

2020年2月3日 · Here's an example LTspice circuit using the current-controlled current-source F1. Value V1 in the attribute editor indicates the current through V1 is being monitored, and the Value2 of 10 indicates the current is amplified by a factor of ten.

2021年4月2日 · Here two examples of how to use arbitrary sources are given with the associated LTspice circuit downloads provided. A Time Stepped Current Source. This can be done with a PWL function, PWL file, or table, but all those things can get rather tedious if lots of steps or frequent editing is necessary.
