Good explanation. Since PWM IC only modulates the puls width and the input is pure DC, it only completes the half cycle on output, not the full sine wave ? Please add the oscilloscope output of the transformer output before the diode.
Bravo! A very informative and nicely explained. One doubt for clarification. As I've understood after having seen your video. The output of secondary transformer is once again AC because of its high frequency of switching (ON/OFF) and once again being rectified by the single diode. Kindly clarify . Tons of thanks
Yes, because of the high frequency switching, the secondry voltage is rectified by a FR (fast recovery) diode and filtered by secondry capacitor. Thanks for your appreciation brother. Please subscribe for more such videos ❤️👍.

Sir, your explanation is very nice. I understood very easily about S.M.P.S. function. But one point is doubtful that is , only A.C. volt can induce primary coil to secondary coil.(as I know) but here input voltage is D.C.in the primary coil of S.M.P.S. tranformer so how dc voltage creat A.C. pulse in secondary coil ? ( I have little knowledge about electronics) . I subscribe ur channel.
A very good and intelligent question. You are absolutely right that a transformer can only work on AC voltage. In SMPS circuit, AC with 50Hz frequency is applied at the input, which is then converted to DC voltage using a rectifier circuit. This DC voltage is then applied to the PWM controller, which by continues switching (on-off-on-off) converts it back to AC with very high frequency of around 32000Hz or 32KHz, and then it is applied to the transformer's primary winding. Hope it's clear now ♥️👍
I have seen 14V smps circuit boards used for battery charging that changes it's led from red to green when battery is fully charged. Can you please explain or make a video of how that circuit senses battery voltage to change led colour? As smps output voltage is constanr, it must be some sort of inbuilt current sensor coupled with smps that stops the current flow (without relay) . I came accross a low power cellphone charger 15 years back that did the same, an led turns green from red on the charger... How did they do that?

Smps design करना बहुत आगे का काम है दोस्त। काफी कैलकुलेशन करनी पड़ती हैं एक एक पार्टनके लिए। इसलिए पहले आप हर सेक्शन को डिटेल में समझ लो की वो काम कैसे करता है। जब ये सब आप अच्छे से समझ लेंगे, उसके बाद ही डिज़ाइन करने की तरफ चलेंगे ❤️👍
