Hello,
I am working on smps boost converter. The problem is that after stepping up voltage and rectifying and filtering it i am getting around 500V initially but than the voltage starts decreasing every second or so and it keeps dropping, i have not connected any load yet. Kindly look into this...
Hello guys,
I am currently working on an all pass filter. I am using 1uF capacitor and 20k pot to vary cut off frequency and the other two resistors are of 1k. I have tried various op amps (tl032, 062,072,082) but nothing is happening. There is no phase shift in the output wave whatsoever. Any...
Hello guys,
Is anyone aware of an IC or module which requires only sine wave as input and generates spwm according to that sine wave. I am actually working on grid connected inverters. Any help will be appreciated. Also can you guys recommend any feedback technique for accurate voltage...
Boost converter problem (push pull)
Hello guys,
I am working on boost conv using push pull topology. The ic being used is sg3525. The problem is that the output pwm of the ic are not square wave, rather the peak of these waves exponentially decreases and then becomes a square wave. Is it...
One thing i dont understand is that how the output DC voltage is increased by varying the duty cycle. I get that the RMS will vary but the rectifier will just convert the -ve portion into +ve of same amplitude. Kindly explain and thanks in advance.
The cct i am using is at the following link...
Hello everyone,
I am currently designing a boost converter based on push pull topology. I am attaching the link to the schematic. The problem is that when i check the wave at the drain of either of the mosfet then the positve peak of the square wave has alot of noise. The peak of square wave is...
Hello, i am current working on single phase grid connected inverter. Can anyone kindly share some research papers for an efficient power share control algroithm.
Thanks in advance
This is the schematic link

Hello everyone,
I am currently working on pure sine wave h bridge inverter. The low side driver output of both sides is working fine. But the high side output is going from 12V and decreases slowly to around 5 to 6V. The sine wave required is of freq 50Hz. I am using ir2110 to drive the mosfets...
Hello everyone,
I am currently working on h bridge pure sin wave inverter project. I am using ir2110 to driver the mosfets. Can anyone tell me if i can isolate my arduino from the power cct using this driver by connecting arduino's ground to Vss and the power cct ground to COM. If not than how...
