In this case , it is only a start up peak and the circuit starts working. I claerly noticed there is something wrong with the original TL494 that came with the batch. Has anyone experienced such ...

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 ...

One of my customers is evaluation TL494. At this moment, they have the following questions. No, we do not. This is ok to estimate based on the datasheet below block diagram after you pick up RT and CT ...

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.
