i explained How to Calculate Inductance or Inductor Value to design High Frequency Transformer to calculate SMPS design discontinuous flyback Switch Mode Power Supply in power electronics very easy. i am am going to calculate SMPS circuit using UC-3843. in this circuit UC1842 UC1843 UC1844 UC1845 C3842 UC3844 UC3845 MC38C42 MC38C43 MC38C44 MC38C45 MC18C42i can be used after making a slight change in VCC voltage. i will calculate all components in the UC3843 SMPS schematic, i distributed the power supply in blocks, so that it will become easy to understand. discussed how to draw a schematic circuit diagram of switch mode power supply and i explained practically. most of the smps designs buck converter, buck boost, forward, feed forward converter, half bridge full bridge converters are same just the switching topology differs. after watching this series of videos you will be able to:-
how to #design #calculate #smps
how to understand smps design calculations for discontinuous flyback function of switch mode power supply, in this tutorial i draw the circuit diagram and placed components and made wiring of the components.
how to repair switch mode power supply when short circuit at input
how to calculate dc buss bar / rail and bulk / main dc / filter capacitor
hoe to select minimum maximum voltage for SMPS
how to design buck boost converter / half bridge / full bridge / forward / feed forward / zero volt switching ZVS / zero current switching ZCS / flyback converter

Thanks for your effort I love your pattern of teaching very very understandable. Sir, my confusion is why did you select maximum duty cycle of 48% and from the datasheet of uc3843 it stated at 100% kindly explain more on it . Thanks

[@jayabratabiswas01]

Sir, Thanks for posting this design series 🙏 I have a question regarding Bulk Capacitor calculations. You have considered Vpeak Minmum for Capacitor value. Why it is? Vpeak Minmum is the low voltage, why we are not considering the high voltage i. e. 375 volt. Other wise Bulk capacitor will not able to filter at high voltage. Please confirm 🙏

hi sir...i saw your video and i want to say you are very good...excusme sir i want make one switching trans..with 220Vin and with +17v 0 -17v and .5amper but i dont know i must use how ferriet and typ wire...pleas lead me thankyou

[@gajendraparmar507]

Hi sir,
Based on which criteria you consider 200khz frequency ?

[@jaylito296]

i have a question sir, the Vmin 85AC & Vmax265 is a constant value that will use everytime i design a circuit ? for example i need output 12Vdc/5A . the Vmin85V & Vmax265V is a constant value that i will use everytime i design a circuit?

[@NARESHKUMAR-ub2iq]

Sir I have a question.
You use here 200KHz it's a typical value or maximum value of operating frequency?

[@mostafasaed4822]

Thank you dear
But I found the inductance equation is different from the one you used.

[@HaseebElectronics]

you are right
there are many approaches to calculate and each technique have its own equations.

[@bartdepauw1156]

Is the 2.5 factor depending on the Design ? So only for 'flyback' mode transformer ? What factor will be used for 'full bridge' mode ?

[@friendman2001]

Where in the videos do you calculate the output capacitor?

[@MachiElectronicsLab]

Nice sir g sir please conform duty cycle how calculated or wh chose 0.48% in explain thanks

[@bartdepauw1156]

Last step ( @11:54 ) surprised me : higher voltage needs a higher inductance ? ( changed from 414µH@100V to 502µH@110V ). So then it should be calculated at the Vdc high ?

[@HaseebElectronics]

No dear
SMPS transformer is always calculated in Worst case scenario (Low input DC rail voltage and maximum power output)
in this situation the IC will use maximum duty cycle. when DC rail voltage will reach at maximum level (i.e 375 VDC) at that time the ic will utilize minimum duty cycle to switch, to produce the same output power (which was being produced using maximum duty cycle at LOW dc rail voltage)
*INDUCTANCE WILL BE CALCULATED AT Vin min*

[@sukhdeosingh617]

Sir kindly make video s on pwm sine wave inverter. Thank u.

[@chandanaranasinghe7197]

why use 0.48 as duty cycle? If we use 0.5 what happens? Should we allow Toff than Ton ?

[@rain0aldwaib]

thank you for this tutorial
but i want to ask
if i want to design my own smps should i fallow all these videos 1 by one ?

[@BajisKitchen]

Honesty is the best policy allah bless you

[@denlo_12]

how is it come 0.48% duty cycle,kindly explain in detail plz Sir

[@MrKumar-il4xh]

One doubt i have, how did derive the Cin cap farmula and primary inductance.

[@sudhakarpatra997]

why taken 2.5 for Lpri calculation

[@rajeshbarlota7134]

If we keep the frequency high the power supply work properly or not because most of the power supply work in 50khz to 75kchz only. But u are using 200khz

Thanks you very much,
small doubt in this video is,Lpri denominator constant term 2.5
but according to my calculations is 2
please confirm it

[@krishnamraaju6442]

NO, V=L*I/Ton
E=1/2*L*i*i
E=Pout/n*t

[@krishnamraaju6442]

so can you tell me,where i did the mistake please
my request

[@chengwan1836]

E＝Pout/n*t, n=0.8 so it should be2.5

[@electronicrepair5060]

What is 2.5

[@sandyblade007]

What is 2.5 and why 48% duty cycle

[@aleksandarjakimov6830]

@@HaseebElectronics but why exactly 48%? Is it necessary to be exactly that number and how that affect our circuit?

[@bartdepauw1156]

@@aleksandarjakimov6830 You still need to have a 'death' time ( both pulses are zero) per cycle. So 48 % is about the maximal time the puls can be high. With the 2 pulses per periode this makes 96% on and 4% off (= death time)
