The final time (Stop Time:) has been set at 5ms because the period of a 1kHz sine wave is 1msec. Another thing that puzzles me is that I had read that the AV voltage needs to be entered as peak voltage, so to emulate 230v AC, I need to enter 325v peak. From: LTspice@ [mailto:LTspice@] Hardware Design. Use the piecewise linear ("PWL") option on the independent voltage source. I have figured out how to measure voltage across a component, but this is still DC voltage. How to plot current vs current graph. Is it bad to finish your talk early at conferences? transfer function, you can just subtract the output voltage dB value by 0dBV, which indicates the dB value of the output voltage equals to the gain. Plot I(R1) normally, then move the mouse cursor over the x-axis, until it turns into a ruler, right-click on it, then write v(2) instead of time. Also, coil L2 was reversed. I tried it on another simpler battery powered HV generator circuit and got the expected 3kv output, however on this diagram I am not seeing what I expected. So just change out the voltage source and vanilla diode in your LTSPICE circuit for a current source, and sweep it across the range they specify. 15.
