i explained How 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.

Sir, upto how much range of power, we can use smps flyback topology, if we need more power, which topology we can use. and i am eagerly waiting for part 3.

Hi sir In bulk capacitor calculation, if we reverse calculate with 68uF capacitor value the ripple voltage will come as 60V. Is the voltage value taken shoul be Vpeak - Vdc min hole squre??

@prashantsharma8627 7 месяцев назад

@kokimkigunku3417 Год назад

Hi, there us a formula from TI for a 12v 4Am SMPS Cin= 2×Pin ×(0.25+1/pi ×ArcSin(Vbulk(min)/√² ×Vin(min))) / (2×Vin(min)² - Vbulk(min)²)× fline(min) Where : VIN Input Voltage 85 --115/230 -- 265 VRMS fLINE Line Frequency 47 --50/60 -- 63 Hz VOUT Output Voltage IOUT(min) ≤ IOUT ≤ IOUT(max) 11.75 -- 12 --12.25 V VRIPPLE Output Ripple Voltage IOUT(min) ≤ IOUT ≤ IOUT(max) 100 mVpp IOUT Output Current 0 -- 4 A η Efficiency 85% My approach is: First, the denominator: 2×Vin(min)² - Vbulk(min)² × fline(min) (2 × 85² - 75² ) × 47 = 414775 Second, the numerator: 2 × Pin ×(0.25+ 1/pi × ArcSin(Vbulk(min)/√2 ×Vin(min))) 2 × Pin ×(0.25+ 1/pi × ArcSin(75/ √2×85)) 2 × Pin ×(0.25+ 1/pi × ArcSin(75/ 120.208)) 2 × Pin ×(0.25+ 1/pi × ArcSin(0.6239)) 2 ×Pin ×(0.25+ 1/pi × 38.6029) 2 ×Pin ×(12.5377) But at the end the power is very huge. That is: 126 = 2× Pin × 12.5377 / 414775 Pin = 2084183 watt My questions are: 1. Is the calculation on denominator correct? 2. Is the calculation on numerator is correct? 3. If correct, is power in that huge?

Sir ...flyback calculation and desing...and flyback driver calculation ...ak video plz

@chinmaybiswas6602 Год назад

Thanks for your informative video. I have one question. According to your Bulk capacitor value calculation required value is very high. Normally we found very less capacitance value in practical circuit. As example it is seen for 48W output power, input capacitor value is 47uF, or 68uF. For 65W power supply, it is generally max 100uF. Can you please share what's happened there?

@windward2818 Год назад

I think the step by step approach is to establish the required capacitor value and it's WVDC rating, although for selection ripple is also very important. For ripple at 100Hz one design goal is to minimize the heat generated within the bulk capacitor due to internal ESR (which depends on which capacitor you choose, from what manufacturer and how it is constructed, you cannot just go by the value calculated). So there is a tradeoff between the capacitor size and its ripple rating or depth (with some added margin because this capacitor has one of the highest failure rates in the design). The choice of 15% ripple for off line is interesting because it was given as a rule of thumb although what is acceptable is the overall design of the capacitor itself. Also, given as a rule of thumb, was an overall power efficiency of 80% (which is reasonable). If you have a thermal camera and examine different capacitors (of the same value and voltage rating but different vendors and types) in operation you can immediately see the heating effect of ripple. You can just simulated the load (converter) with a resistor. Some, input capacitors will get very hot (above 80 C) other will run a lot cooler depending on ESR. This is why the recommendation was for a 105C capacitor and not an 85C rated capacitor the author wanted some margin. But, in actuality, the capacitor you choose at a given worse case supply power should run as cool as possible in order to maximize it's life (temperature versus MTBF). So, what you will find, if reliability is a factor, the capacitor value will be very large in comparison to the calculation. Also, the WVDC rating of 400V assumes to a certain extent that any fast AC line transients beyond the surge voltage rating of the capacitor is minimized on the AC side using a MOV. So, in a way the design is assuming the rating of the capacitor will not be exceeded. And, it was also mentioned that the capacitor would have a current surge (supply surge limiter) using a NTC Thermistor. Which minimizes the surge current into the capacitor.

Sir, you are using 3843 ic. Will this calculation change if we use some different ic.

@Gary-ts6dh Год назад

6:08 - Setting the frequency to 200 kHz instead of lower will minimize rise time, as you said. But, since the higher the frequency will be the shorter the rise time will be, what would be the drawback if you wanted the frequency to be as high as 500 kHz? Where would you draw the cutoff line?

@martym2464 Год назад

I agree, I wish he spent a few minutes on all factors deciding the frequency... not just rise time.

Can we use the over value for the capacitor rather than the calculated value .... I mean calculated joule increase up to more than 50%. My expectation is capacitor life & life expand. Is it correct

@suatkaleli5075 13 дней назад

sorry but today I rechecked the video and I have the smps battery charger circuit which has input value 220 AC and output is 84V DC and 8 A. In accordance with the video I calculated that the cap. value should be about 3800uF however this circuit has the double cap with the value of only 120uF and circuit works fine.

@joselattuf1564 Год назад

Good day from Venezuela south America. I am engineer in electronics . I am interested on this video to design SMPS power supply . I suggest to you if may I say : what don't you use a magic black board to do this tutorial about designing this power supply . I can not see what yiu write on the paper . It is difficult to get all the information from the paper you are using . The numbers and letters are to small .
