Re: power dependent resistor - thermodynamic model
Hello, As far as I know you cannot link user code to LTspice. However, LTspice can be used solve ordinary differential equations, difference equations or z-domain problems and most other algebraic

Re: power dependent resistor - thermodynamic model
Thanks Mr Bordodynov for the tips, i saw enough information in the lib section to accomplish the first step. An other question: Anyone know if there is a way to link ltspice with an other program to

Re: JFET Model
You are mixing several effects in your question. A Clapp oscillator is a special case of a Colpitts with an added decoupling capacitor between the main LC tank resonator and the grid/base/gate

Re: JFET Model
"I am not sure, but it is pretty likely that the JFET spice model does not include the voltage dependency of Cdg." Actually, I believe the SPICE models for most transistors, including JFETs, are quite

Re: A three Phase question please
John, Jim's original message stating that the 2 wattmeter method doesn't work was not very clear, but it won't work for a Y system with the neutral connected. Blondell's theorem states that you need

Re: power dependent resistor - thermodynamic model
Hi Micha. In this group, there is information dedicated thermistors. There is an option which takes into account the inertia of thermal processes. Look thermistors "NTC" and "PTC". You need to replace

Re: A three Phase question please
John, Your method relies on the vectorial sum of voltages and sum of currents in the branches being zero, which is the case in a delta or floating-Y connection. But when both the source and load are

power dependent resistor - thermodynamic model
Hello, I'm trying to simulate (transient run) a power dependant resistor, the resistor is used to dump an high energy capacitive bank (like an RLC circuit). During the fast discharge, the resistor

Re: A three Phase question please
Jim, If you implement the 2 wattmeter method correctly it works fine. If one phase has a huge power, it doesn't matter. Rick
