How to design a EMI filter for an ACDC power supply?
I don't want any ready made filter. How do I know if a filter is enough or do i need to a change?(I don't have any now)
Thanks
Hi,
In the below link each topology has the power and current limitation.

What makes this limitation? Why can't we produce an smps with 150W and current higher than 10A with flyback topology?
thanks

Check the Switching frequency and ripple frequency caused by TPS82084. You should use a filtering of atleast 10times switching frequency. You can also use a TVS in case of a surge appear(ESD).The Raspberry Pi uses a SMBJ5.0A device to suppress transients.
You may need to put the ferrite bead to...
HI,
Short circuit /overcurrent implementation can be done by adding a sense resistor at the source of mosfet and setting the maximum peak current of the transformer. Always choose the current protection 75% of the saturation current of transformer. This also works with short circuit. How are...
Fast blow: because in case of spikes appear at input it should not damage the converter.

Hi,
Schematics 2 a diode is placed inorder to avoid the negative spikes on the base of transistor.
how does the diode between collector and gnd act as a snubber? you need to provide a diode between collector(anode of diode ) and red dot of transformer (cathode)...
Hi,
First of all what is documentation symbol?
As per my understanding its a format for schematics sheet.
Now for a documentation sheet how to add Logo, date and sheet no. in CADSTAR V8 and how can I make rectangle with my dimension.
Shape properties shows the following "attachment"
Thanks
1. 1/3 means there are 3 coils for transformer 1.primary 2. secondary 3.auxiliary.

please find the design in above link.
Now when the transistor turn off the the...
