Does this buck and boost will effect the connected gadgets? because it might be very dangerous from my aspect....do you have any clarification...My load is an Air conditioner
Very informative video Sir. Cleared a lot of doubts that I had. Well, I am looking for a high capacity 230-120 V step-down transformer preferably in excess of 1.5KVA. Need it for all the power tools and AV equipment that I bought during my time in the US. The ready-made ones are kind of expensive and don't make sense considering their engineering and copper/metal input costs. I have two 4KVA good quality ( copper wound ) voltage stabilizers lying around. They are rated to work in the 125-280V range. My research on voltage stabilizers makes me imagine that I can use the 125V taps from the auto-transformer while hooking it up to 230V mains supply. Am I correct in assuming this? Looking forward to your reply.

Chattering is owing to bad circuit design. An arrangement called hysteresis has to be provided for each relay drive. Hysteresis is a situation that for example if the relay change over happens at 180 volts it reconnects at 184 volts, not at 180.5 volts say. This 4 volt is the hysteresis. This is achieved by providing feedback from output to the input by a high-value resistor of about 150k to 330k to provide a hysteresis of 4 to 2 volts respectively. Without hysteresis for example if the voltage hovers around 181 to 180 to 179 the relay chatter happens. some temporary solutions can be by connecting an electrolytic capacitor of 100uF to 470uF across the relay coil with proper polarity. But it may or may not be a solution as several other factors are responsible. I will make a video soon on this for better clarity.
Mrunal Ahirrao Basic principle of transformer is input power =( output power x the efficiency). Thus whether buck or boost the current will vary as per the voltage. Example let us assume efficiency is 100% for ease of calculations. So input = output. Then input 200 volts x 5 amps at input= 1000 watts .If we boost it to 250 then 250 x 4 =1000. Or in other words if the input is 250 and we buck it to 200 ,the input current is 4 and output current is 5 . As simple as that.Engineers should not ask this simple question.
Patnaik UC Sir I am not asking about transformer current, for example I want to connect refrigerator which consumes 700mA when ON, so suppose I used 12V,500mA transformer to stabilise, and I boosted the voltage from 218 to 230 using above transformer, so the load current what about load current will my stabiliser supply enough current for above refrigerator?
Mrunal Ahirrao It is not the current alone that is required to operate a load. It is the power ie voltage multiplied by current. So if your transformer is 12 volt and 500 mA the total power that the transformer can handle is 12 x 0.5=6 VA.Whatever way use that whether step up or down the power delivery in 100% efficiency cannot be more than 6 VA. A standard 165 liter refrigerator but needs minimum 600 VA which is 100 times that this poor transformer can deliver. So no way that you can sue such a transformer.
The output is between "-" and "-" and not parallel to input as you have wrongly conceived.Thus it subtracts the secondary voltage 12 from the primary voltage 230
Okay, I watched it again.. 1. The Boost is connected in Direct series. 1A (inductive series may differ, depending on coiling direction) 2. The "Buck"(#GoVegan), is Directly Connected in Parallel. 2A (if the inductance is coiled in same direction, they self intensify eachother, equally, when current increases. And they self limit eachother equally when the current reduces). 2B (if the inductance is coiled in opposing directions, they limit eachother,when the current increases; the in current favor coil is less effected. When the current decreases the 'favored' coil is more affected?) Either case both are connected in direct parallel, but I suppose unequal charges will occur if inductors are not coiled in parralel.
Sorry. You have again gone wrong. The question of parallel connection of the secondary coil to the primary coil doesn't exist at all. It is series and series only whether boost or buck. The series coiling (the secondary) just changes its direction while from boost to buck or vice versa to add or subtract the voltage while parallel coil (that develops the voltage at the secondary) remains at direct supply always permanntly
Sir the concept is really amazing and the simple way you delivered it for easy understanding is more than amazing. I lean before you sir.
My goodness. This is good. Never knew this
Thanks. My pleasure
Well explained sir, Very clear and upto the point explanation. Thank you
My pleasure
Very useful video👌
Thanks
Clear cut concept
thanks
It's a bit like a biofeedback restrictor.
Sorry. I don't understand

@@PatnaikUC Thank you Sir , nicely explained. Awaiting your video.

And what about load? will the Boosted/Bucked voltage will supply same load current?

very good explanation sir
Pavan Kumar Thanks
sir, do you hve desing for servo stablizers?

No. Please post your query ucpatnaik at gmail dot com
thank you very much
My pleasure
very usefull jobs. THANK YOU !
Thanks. Pls visit my website www.projectntraining.com
The "Buck" was solid connected in parallel. The voltage would have been equal.
Sorry you are wrong. Pls watch the connections again.
The output is between "-" and "-" and not parallel to input as you have wrongly conceived.Thus it subtracts the secondary voltage 12 from the primary voltage 230
Okay, I watched it again..
1. The Boost is connected in Direct series.
1A (inductive series may differ, depending on coiling direction)
