Hi, I construct an inverter using sg3524, when I power it up and measure the output of the sg3524 to get the idea of the level of the pwm voltage output, the reading I got are as follows;
input voltage=12v
Pin no. voltage readings
6 ----------------------3.75v
7-----------------------2.25v
11----------------------5.89v
14----------------------5.89v
12,13,15---------------12v
16----------------------4.99v

As i don't have an oscilloscope, I can verify the output waveform. So, i want to know, if the readings I have above (using digital multimeter) are correct. And if not, what could be the problem.

Note: according to sg3524 manufacturer datasheet
Vce(sat) = 2v
Vc = 18v @ Supply(Vdd) =20V

hi. you must use oscilloscope to analyze the PWM voltage waveform. If you see a square wave from the oscilloscope ,it can be said that the sg3524 works clearly.
 

You can get a serviceable oscilloscope on somewhere like ebay for $100. Not much excuse to not have one nowadays!
 

Hi,
These are fine and you can tell even without oscilloscope, that the SG3524 is oscillating fine. Now you need an oscilloscope to verify other facts like if the wave shape is fine, are other things causing it to be distorted?
However even without this, you can go ahead and use this for your circuit.

Hope this helps.
Tahmid.
 

Your output of SG3524 is ok,as tahmid said you can go ahead and start your inverter construction.
