Apne T1 and T2 ka colecter ko emmiter our emmiter ko collecter bola hai. O dono ka pin sahi dikaya hai lekin naam ulta kor dia. Jo pin arrow se denote hota hai o emmiter hai, or arrow nehi hai to o collecter hai. Overall apne bahut accha samjhaya hai.
If 2 nos diode are used for rectification,this is known as half wave rectification,if 1no. diode is used for rectification this is known as quarter wave of rectification, If 4 nos diode are used for rectification known as full wave of rectification More over Ripple charges are filtered through Inductor and capacitor,thanks for knowledgeable SMPS power circuit video,It will be prolonged,thanks.
If one diode is used it is called half wave rectifier. If two diodes are used it is full wave rectifier (in this case centre tap). If four diodes are used then it is called full wave bridge rectifier.
Awesome explanation. Bhai 2ndary me jo bari coil lgi ha, meri power supply me wo burn ho k dark brown ho gai ha aur supply on nhi ho rhi... Can you tell me how it can be repaired? or make a detailed video. thanks. Also outer 2 schottky diod lg rhy lekin middle me transistor lga hua ha I think.... Thanks
Sir, After the rectifier the voltage will be about 170volts across each big electrolytic capacitor. In the video, you say 12V. One has to be careful because you will get a shock.
Thanks for your input. Learnt a lot as you tried to explain with schematic which generally youtubers don't do. Infact, some of my doubts got cleared. But, please don't mind there is a catch! Like others tried to bring out some of the other issues they noted. Likewise what I noted is that, not only as you figured out the connection points of Transistors, you have marked collector, emitter wrongly in the schematic; atleast, denoted wrongly in my opinion which may bring serious hazards if someone follows blindly at 15:24. Emitter is always the one with arrow, may it be in any direction. Collector has no arrow in it. Emitter which is heavily doped and which emits electron in the circuit. And this direction of emission of electrons are showing with arrow inside Transistor symbol. Collector, as the name suggest collects Electron and hence, has no arrow marking in it. And Base is like a Gatekeeper to me who checks the ticket (sees biased voltage across it) and allow commuters to enter into platform, or similar. Hope you will take care these things in future videos, because these are fundamental errors which is not at all acceptable. My writing to you is not to defame you but alarming newbies Thank you good Luck!
