in this video i demonstrated how to calculate & design TL494 Dead-Time & Soft Start Circuit, Practical & Calculation #TL494 / TL495 pulse width modulation control ic in switch mode power supply or ATX computer power supply. i explained how to use this ic in push pull mode to drive half bridge or push pull circuit. it can be programmed from 1KHz to 300KHz switching frequency . its frequency depend on RT timing resistance and CT timing capacitor
the deadtime function generates a off periode between the switching time of both mosfets. most commonly the amount of soft start is allocated for 25 to 100 switching cycles.
this is continuation of inverter circuit, tl494 is smps pwm pulse width modulation controller ic to drive push pull driver, it can also drive half bridge

More clearly now after waching this video, especially on no4 pin (DTC) - waiting for video controlling op amp as current sensing, I tried modified several PSU , it worked on controll voltage but always failed in controlling current. It give me @only 30w instead of 200-300w as I expected. Thank you for nice presentation video & waalaikum salam, dear brother.

Great, Haseeb! I tested the soft start on single ended mode. But my wave only increases the duty cycle, not the voltage, like yours. All range is 12V...

@HaseebElectronics 2 жыл бұрын

good morning dear i will check it if it is changing the duty cycle, that is good i will recheck again, i think voltage will not change it will change the duty cycle i will check again and will reply

A real light bulb moment for me with this video, thank you for the clear and detailed explanation! I have one question. You demonstrated that the pulse width could be modulated by either the duty cycle or the dead time control. SMPS design utilizes the duty cycle method to control pulse width, what is the reason for this? Hope that makes sense?

@bartdepauw1156 Жыл бұрын

But Rs forms a voltage divider with the R parallel with the Cs, so pin 4 will never go to 0 V. Is 100k ohm feasible to be as close as possible to 3 % dead time or can it be even higher ? (100k is C discharge time of about 0.2s )

Salaam sir, I am Israr Ali from Hyderabad Sindh, kindly guide me about my Rigol DG2041A function generator. It was after shown a message on screen (overload waveform), and suddenly disable square and pulse waveform at output terminal but showing voltage on output terminal, and other all waveform are properly appearing on output terminal, so kindly guide to me that, how can enable square wave and pluses wave on output terminal?
