Hello once again brother Haseeb! Another Excellent amazing video. Very well presented and you covered every detail and answered the few questions I did have about “Flyback switching power supplies”. You are truly a gift to the world of electrical and electronics to those who have a sincere desire to excel in this field weather it be as a technician or on the level of engineering. I can appreciate this particular video because it was the “Flyback switching power supply” that gave me my introduction to switching power supplies 12 years ago when I attempted to repair my 21 inch CRT JVC color receiver. JVC on it’s web page had a very detailed description of the theory, physics and workings of it’s “Flyback power supply “. It took many re-reads but I grasped the concept. The actual control of the amount of energy needed stored in the magnetic field being switched by a mosfet power transistor through pulse width modulation at the command of the amount of feedback via TL431 and opto coupler. With the help you have provided by going into deeper detail as to how the TL431 is more of a programmable voltage regulator, the snubber network and power factor correction and all the detail calculations have truly made me better and more confident. Thank you brother!

Dear , I love your way of explaining . Kindly clear the design aspect of aux winding also. The cap , once started chip , voltage will also appear on aux winding and it will hold the current to chip. Cap will start discharging only when aux winding is unable to provide enough current . So what is design aspect of aux winding. Thx.

Excellent video as they all are. Question...with regards to power, and dissipation of the startup resistor, aren't we only talking about a period of milliseconds, where current flows only from the startup circuit? I mean, once the controller starts, the aux winding creates a similar voltage, and the bias across that startup resistor goes o near zero, dissipating almost nothing, correct? Pardon me if I missed it, or misunderstand the issue. Also, I noticed many designers like to stick with 1/4 watt resistors, so they series connect 2 or 3 or 4 to spread out that startup dissipation, I guess it's cheaper.

Sir you create videos that we dont find anywhere on youtube. Haseeb sir you have covered major calculations on every components. I have a situation. I have an smps where the output capacitor is blown completely. It is 12v 4amp smps. How will i know how to calculate the capactior Volt and Micro farad for this smps? I hope you understood my question. Haseeb sir mein yeh jaanna chahta hu ke kaise hum capacitor volt or microfarad decide kare circuit mein. Many times same volt capacitor we get but different micro farads. Can you throw light on this topic?

Thank you very much again!!! But can I ask shouldn't be R= Vin-Vcc/Icc, being Vcc the voltage consummed by the IC, like when we calculate the R for a Led? And, when it comes about the UC3842, how can 16 volt turn it on, since you've told that it has a 34 volt internal zener diode, shouldn't the Vcc voltage be greater than the zener voltage? I ask you this because I've been studing the UC38xx data sheet and noticed this. Thanks a lot; this channel is answering me a lot of questions. I really appreciate you tutorials. I'm always looking forward your videos.

@HaseebElectronics

3 жыл бұрын

you are welcome. all these points I have to discuss in upcoming video to discuss internal zener and external zener circuits (that is the 2nd part of this video) amps controller have to working regions 1. startup 2. normal working 1. in startup the current will use to charge the hold up capacitor. in tht case we have to use R=Vin min / Istartup. because I'm startup the vcc pin will start from zero volt upon reaching at 15 to 16 volt at UVLO-on threshold, ic will start switching. then it's uvlo circuit will enter in operation mode, I WILL EXPLAIN IN UPCOMING VIDEO the internal zener is 34 volt. that is used as a voltage clamp for protection. to protect this ic to reach at extreme limit (34 volt) an external zener for range 18 to 28v is used at vcc pin. that will protect ic from damage. we will discuss in upcoming session

JZAK ALLAH JNAH ALFIRDOOS MR HASEEB. My wondering is that ok when IC take voltage from startup resistor first then when IC work so it take voltage from axillary winding, where the voltage coming from startup resistor goes into the resistor so voltage drop so heat dissipated in my head its like to voltage head to head i need to understand and i hope you understand me because i have project to do in my university

Good evening please check video number 954 and if you have any question, you are welcomed

Sir, can u please explain regarding bootstrap circuit in High side IGBT driver.

Sir can u explain how to organise components placement in pcb design for proper functioning of SMPS.

I used this method for start up resistor calculation and the IC didn't start up because all the voltage dropped in the resistor just few millivolt passing hence using the formula R = V/I simply means the voltage drop accross the resistor must be equal to the product of current flowing through the resistor and the resistance of the resistor. It should be: R = [(Vin min - Vic)/I] I is the startup current

Is same formula used for Constant current power supply ?
