Yes, correct gate is auto biased for full AC signal (no phase control) & just switching mains voltage to load ON/ OFF which is main function of ACST rather than phase control. jagdish

Yes, ACST device is bit different from Triac. It is specific AC switch just used to ON/OFF mains supplies to load.? Some more information about that,

Hello Andy, I will take care of no uploading RAW or LOG or . NET files. Also I am aware of fixing time step too small errors, thanks for providing the document again. However, my basic idea here was

Fred, By moving the ground connection from below C1 to below V1, you also need to change your .IC statement, so that the initial voltage is applied across the capacitor: .ic V(C1node,N002)=0 You don't

Hmmm. Like I said, I have a lot to learn about the software. I uploaded capacitor_charging.asc to the files section. What I have in that schematic works. I can create a current probe in the resistor

Fred wrote, "I figured you could only have one ground, but put it on the input side based on examples from the web" Yes, if you have more than one ground, just be aware that they get connected

Thank you for correcting my mistake in posting. I was coming back to say I found the issue and have a tad more to learn about LTSpice. I figured you could only have one ground, but put it on the input

Someone named "FlightRisk" attempted to send a message to the [LTspice] group an hour ago, wondering why there are "wild voltages and currents" with her/his rectifier circuit.? But they probably did

Over the years I've noticed all versions of SPICE appear to use different algorithms to solve the DC bias point for .dc, .ac, and .tran analyses. The use of the .savebias and .loadbias commands can be

I would separate this in two answers: 1) if you are getting from a manufacturer a *standard transformer-* ask your manufacturer for supporting you with measured data about the specifications given.And

This is something that has puzzled me too, for years, but I did not figure out how.? Also there are cases where the initial operating point solution needed for .TRAN differs.??I think the

Ohms per volt is a figure of merit for moving coil voltmeters. The number is dominated by the resistance of the moving coil; that is the input resistance on the most sensitive scale divided by the

Hello! Question is simple, I have a circuit (I can't upload it here due to company restrictions unfortunately), and it perfectly converges in DC analysis, even if I start it not from the zero voltages

Jerry, Thanks for your comment, I didn't know that the inductance decreases at higher frequencies. The modification of the model to correctly reflect the decreases at higher frequencies is beyond my

Ohms being Volts per Ampere, Ohms per Volts would resolve as 1/Ampere. As you say, I don't know that a unit has been deemed useful for Ampere power minus one

Equal to x peramps?? While resistance, capacitance, reactance and impedance have inverse units (conductance, elastance, susceptance and admittance), I don't know of any for inductance, voltage or

Thanks Dave Bell.

Well, it’s the reciprocal of current, which is a rather obscure unit. It used to be common as a figure of merit for (analog, moving coil!) milli- or micro-ammeters. The higher the number, the

Is there such a thing as x ohms/volt?

To be clear, I am not talking about the sort of 'design' posted by ik.weide. I mean choosing the core size and material, and the number of turns of the gauge of wire that will fit on the bobbin.
