One additional wrinkle not (at present) mentioned is that Class X and Class Y capacitors are used in those specific locations for safety reasons, having to do with the capacitors being connected di...
The simplicity of zero-crossing measurements is attractive. Regarding "Full period" zero crossing (i.e. time between rising-zero-crossings, or between falling-zero-crossings), compared to "half pe...
Hello, I want to understand the math of the phenomena of capacitor as temporarary means of increasing the current supply. First I have created a current limited voltage source which give me 45V a...
Hello,i need to drive 5 mosfets as shown below. Each mosfet draws 15A when the pulse opens the mosfet. My power supply is gives the 48V but only 3.3A,If I understand correctly I need to put very...
For my opinion, it is not too complicated to reduce the various equations to a system of two equations with two unknowns (current Ib2 neglected), Let me try: Vb1-Vx=I5*R5 I5=IC4+Vb1/R3 IC4=Ue...
If this is a contrived homework problem where they are looking for an "exact" answer, then you have to solve a bunch of simultaneous equations. However, that would be neither useful nor anything y...
I'm having trouble using the nodal equations to determine the base voltage Vb1 in the circuit below. I've attempted to write seven equations below, but not able to fit them in entirely. (12-Vx)...
Hello,I want to simulate a delayed pulse going from 74ABT04 to the load which is UCC5304 where load with 400K i think. but my pulse source 74ABT04 is not an idial voltage source as shown in the s...
are there more elements contributing to this effect that I have not placed in the circuit? Definitely, but it's hard to say how relevant they would be. The real world is messy. There is parasiti...
are there more elements contributing to this effect that I have not placed in the circuit? Well, you have a simulator and it should be really easy to remove C_windings and observe if the ringi...
For my own understanding I tried modelling switching off an inductive load without a freewheeling diode to observe ringing. This is the model I used: 1.) Are the two main components of the reson...
Why are CY capacitors on the source side, and not on the load side? You may not be grasping what the image shows. The left-side port connects to the AC power-line. It supplies power to the rig...
There is no "standard". Do whatever works best for the situation at hand. In a microcontroller, it's usually easier to measure period than frequency, especially for "low" frequencies like the pow...
For easy reference and to protect against possible edits to the question, here is the circuit you are asking about: In order to attenuate a signal, you need two impedances. Imagine you had a 0 ...
A circuit under question: Why are CY capacitors on the source side, and not on the load side? Henry Ott describes this with: “Because filter attenuation is a function of impedance mismatch, th...
If you're talking oscilloscopes, I used to do peak-to-peak measurements for the time period. And then, as you note, invert for the frequency.
In a general sinewave as below, is there a "right" way/"standardized" way to measure line frequency - and how do energy meters calculate that? measuring pulse width of half-period, ie. time elap...
There is no provision in FatFS or the fat32 filesystem in general regarding hot-unplug, so this behaviour depends wholly on the implementation layer for your hardware. As an example, in my use cas...
Consider a device with a microSD card. The microcontroller writes to the SD card periodically. The operators have an ability to remove the microSD card at any time (they will be removing it every...
The flashing-light frequency shall be 90+/-30 times per minute. I don't know what could be more clear. This spec says that the light must flash 90 times per minute, ±30 times per minute. In othe...
I was analyzing the design a hazard warning light.The spec of the light turn on off is given below. The flashing-light frequency shall be 90+/-30 times per minute. May I know in this case the...
Your question is ambiguous. First, you need to define "rise time". That applies to a step, not a periodic signal. Let's say you have a 0 to 5 V digital signal. The rise time is how long it take...
May I know how to calculate a signals rise time from it's frequency. I found this article for the same. The formula given is Tr = 1/f*π. May I know is this applicable for PWM also.
Every real part has resistance including your piezo current source. Every switch resistance is a loss in energy (I^2 R * t)=E and includes diode and transistor switches. What you need, I think, is...
I'll take it that you want this circuit to actually work, not just appear to work in some software simulation. In that case, it's about the circuit, not the simulator. A simulator is just one too...
