I have some pictures of the full-featured variable 500-2000vdc push-pull circuit but they do not show the bottom circuit board or discuss the responsible part in the calculation of the transformer. I tried other fans and the same thing happens but if I have a tv connected at the same time with a fan I do not see much difference between the picture on the screen or the TV so I do not know how to explain it so I ask you.

SMPS circuit SG3525 and IR21 integrated on board MOSFETs IRPF450 transformer with ETD44 response 4N33 opto-Kubla with associated. We used voltage between 1-5V to pin1 and the PIN connected to pin 16 with one ohm counter but error amplifier output on pin 9 is not correct which is only five.Sincerely Tahmid.

Delete Dirlean R Santos September 4th 2013 at 10:22 Pacific Time in the United States I trying to create converters use SG3525 as a PWM controller for wind generator that will work with variable voltage from 80 to 240 VAC and output voltage inverter should be be 50Vdc the power to be very high in each module would be timing to connect the units parallel to the converter set without scheduling they do not function fully PWM pointer effect on others. In addition the oscilloscope becomes difficult to understand the nature of spikes but you can experiment with different values to find the one that works best. When he saw a block diagram in the datasheet I realized that the response signal should set the reference current as combined with the sawtooth. Instead of winding 4 turns moving the center tap out and winding another 4 turns I decided to break both secondaries to keep them symmetrical as much as I can.
