PWM circuit diagram with SG3524N

04/26/2007 11:49 AM

hello

who can help me with a circuit diagram of an oscillator using SG3524 to generate a pulse width modulation of a frequency of between 50 and 60Hz. This is to drive power MOSFETs like IRFZ44 or higher one for a dc to ac inverter.

if other details will be necessary i am ready to supply.

OK, If you want to create 50/60 herz AC from DC, the best way is a switching PWN waveform synthesizer that uses power fets to create a waveform of the required profile with high frequency 20-100 Khz pulses that insrease/decrease to create the sine wave and are followed by a low pass filter that blocks the highs and let the 50/60 hertz though.

this company makes one
