A possible cause for your problem is that you are putting the reference of the oscilloscope probe in the bottom part of the resistor (load). However, the osciloscope probe is grounded.
So, use a diferenttial probe or remove the osciloscope connection to the ground pin of your AC outlet (maybe...
There are inherent losses, yes. These can be basically divided into 1) electrical losses and 2) magnetic losses.
1) The electrical losses can not be avoided since the windings will always have a series resistance, Rs. You can minimize it by improving conductor properties or by increasing wire...
One could use epoxy resin to fully protect the electronic circuit. This is very common in the electronics industry.
To simply protect the printed circuit board against moisture, try conformal coatings such as the Loctite Shadowcure.
If it is not possible to fill the complete assembly with...
It would be really long answer, but some topics are:
- Smart grids;
- Quantum computing;
- Nanomotors and nanorobots;
- Wireless power transfer;
- Wireless sensor networks;
- Cloud computing;
You will find the most popular articles on IEEE library (they give you an idea of what are...
The fan is an electric DC motor. Applying a voltage higher than the rated one will cause the fan to operate on speeds above the nominal and this could cause the fan to failure due to excessive vibration or incur in a bearing failure (both would take some time to happen). Electrically, the...
I just realized that multiplying the inductance given in Maxwell 13 by N2 the result is the desired inductance... Is it possible to obtain the result directly ? I mean, isn't it possible to enter number of turns in Maxwell ? This is a simple axisymetric problem.
Also, how can I get induced...
Try a SLIM, Single-Sided Linear Induction Motor... it's interesting, has good EE theories (mainly about motors, of course), but requires a nice mechanical design too.
John,
Power inverters are based on controlled semiconductors, that is semiconductors that turn on and turn off depending on the control pulses. These semiconductors are usually MOSFETs or IGBTs, both are transistors (the final "T" stands for transistor).
In a single-phase inverter you...
Consider the voltage over the upper coil as v1 and over the other coil as v2.
The center tap of the transformer can be considered a reference point. So, if you simply "ground" it you will understand that that point is always with 0 volts (as it is the reference). Then, when the voltage supply...
Hi,
You should look this on-line simulation tool:
http://www.dee.feis.unesp.br/docentes/flavio/lepjava/index.php?id1=2&id2=0
Select the full-wave rectifier to simulate your circuit. Click "anime" to see operational stages.
Anyway, you should look for basic diode...
Hi everybody,
I would like to compare inductance (self and mutual) calculations using FEMM and Maxwell 13, both 2D problems. In FEMM this is very simple and I just use an axissimetric solution, enter the desired frequency, currents and get the results.
When using Maxwell...
