Why are smaller ratio current transformers physically larger than bigger ratio current transformers?
During a presentation on current transformers yesterday, something came up that I really didn't start considering until today. The presenter said one of the biggest issues with using smaller ratio current transformers (i.e. 200:5, 600:5) is they…

What is the importance of peak factor and form factor?
I get that form factor and peak factor are suppose to be ratios involving the RMS, maximum and average values of current or voltage for AC circuits, but I don't get specifically why those ratios are important that they need a special name. Is there…

9 V to 360 V via boost converter?
So I'm fairly new to electronics and I wanted to make a boost converter. I was trying to get 360 V from 9 V and ran my circuit through LTSpice and EveryCircuit but it didn't seem to work.
It's a typical boost converter setup and I just have the…

Doubt on PSRR calculation and result
I designed the following circuit in Cadence Virtuoso:
It is a two stages op-amp with a compensation network (resistor and capacitor). VDD=1.8 V, VCM=900 mV, VB2=1.28 V.
The DC gain is 73 dB.
1st question: I have to calculate the PSRR (power supply…

Is there a practical use for the Fibonacci sequence or similar fractal/sequence in Electrical Engineering?
One use of Fractal Engineering is in Fractal Antennas:
An Overview of Fractal Antenna Engineering Research
Abstract:
Recent efforts by several researchers around the world to combine
fractal geometry with electromagnetic theory have led to a…

voltage transfer ratio
I painted the currents, used the first Kirchhoff's law and got the expression:
Next, I need to find the voltage transfer coefficient (Ku), that is, the ratio of the output voltage to the input voltage, but I do not quite understand how to do this…

Impact of Transformer Ratio to Performance of Transformer
Based on my initial calculation, the primary inductance of my transformer will be around Lp = 351uH. This 351uH is designed with switching frequency of 55kHz for AC-DC flyback converter (DCM). By using LT SPICE, I will get result as below:
Primary…
