PWM ,3 channels ,resonance frequency,spectrum analyzer,adjustable duty cycle

 

 

What PWM  solution(with MC Programmer ) is possible to use    for  this caracteristics ?

 

 

- control/adjust frequencies from software

- feeadback option /spectrum analyzer to find resonance frequency

-3 channels with difrent frequencies (42.8 KHz, 21.4 KHz and 10.7 KHz )

- Adjustable Duty cycle /pulse with 2.5%,5%, 10% , fall time <=20nS

-Up to 500 Watt

 

 

 

 

PWM Comparator Section  FEEDBACK    0.3-5 V
Switching  Characteristics  Rise time  :100-200 ns  ,Fall time 20 - 100 ns
 
 
I looking for a replacement  of TL494 form Texas Instruments   with a MC solution
