in this video i demonstrated how to design #TL494 / TL495 pulse width modulation control ic in switch mode power supply or ATX computer power supply. i explained in urdu hindi language . 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
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
in this video i demonstrated how to design #TL494 / TL495 pulse width modulation control ic in single ended driver to drive flyback topology, forward converter, boost converter operation
i shared calculations process to set frequency,
how to select timing capacitor value,
how to select timing resistor value
what is dead time
howto calculate dead time
how to adjust dead time
how to set frequency of smps
