I am using a TL494 to generate PWM for a flyback converter. I want a variable duty cycle between 10-90% using error amplifier. I tried the configuration in the ...

At its heart is the ubiquitous TL494 PWM controller that you may be more familiar with in the context of switching power supplies, this one applies the audio drive as PWM to the gate of a MOSFET ...

To get these currents into a workpiece, [bwang] used a TL494 PWM controller as an oscillator. The output of the TL494 is filtered and amplified a few times to generate a huge amount of AC current.
