Off topic When I started designing and producing mains stabilizers for the local consumers, around 4 decades ago, I used LM324 with trimmers to activate the relays properly (much like the one discusse

Hi, The following is somehow off-topic. Lately, I was asked to build a charger for 24V acid batteries. The source is a high-volt solar panel (PV). I uploaded the basic circuit I thought of for it (Sol

Hi, For instance, I used to add a rather long list of (.meas) commands in most of my projects (to analyze the simulation results later on Excel). So, I put their list on a separate text file and inclu

For instance, to check the edge cases for charging/discharging an acid battery, I simply use a constant voltage source and a capacitor in series. By using a capacitor in series, the slope of the VI ch

For instance, since most of my simulated circuits contain a power iron transformer, I used to vary, by trial and error, the initial phase of the source sinewave till the DC current offset becomes clos

For instance, I used to save a screenshot of almost every schematic I design (there are thousands) besides its plot window (combined or separated). When I start a new design which is usually related t

For instance, on my side, getting the error, 'timestep too small', is 'also' a sign, to me in the least, that one part (or more), in my design, is not practical really. In a such situation, I simply r

As you know, John Chan model of a non-linear transformer is defined by the parameters: Hc, Bs and Br (besides A, Lm, Lg, N and Rser). I just wonder if there is a simple example/schematic by which the
