thank you sir . it has fix my problem . before connecting load my output was 23.8 giving input 24v.and now 9.92v is output giving input 24v. but there is still problem, that is i need 14v out and in this circuit my output is 9.92v.
i have changged the value of inductor and duty cycle very...
thanks alot to all for reply me.the problem has been fixed.actualy capacitor inrush current was high than fuse ratting thats why fuse eas blowing...againg thanks all of your reply..
hi to every one ....
i want to design buck converter and my requirement is to convert 24v to 14v . first calculate the values for inductor and capacitors from formulas given by microchip .and now i am checking it in proteus but my required result is not obtained. please help me it is my smester...
hi ...i made a simple rectifier circuit . but there is problem that when i supplies power to circuit then fuse get blows .every thing is fine no short circuit ,circuit looks fine ...what is the problem please help me it is my project part. this circuit is given below..
thank u very much of all of your replies...actualy acording to formula 1/Cf(0.7Rt+3Rd) i recalculated the values and i put the value for Cf =0.1nf and Rd=0 in the circuit and by calculating the value of Rt for 20khz was 0.714Mohm . and i was using mistakenly :-( 1k ohm. now i am strongly...
thank you very much of all for helping me..and i am very glade for helping me, fvm. but sir i have connected potentiometer with pin 6 of 1kohm , when i set the value of potentiometer to minimum (mean zero) then frequency is 400khz and by increasing the value of potentiometer the frequency...
hi , i am new in electronics and my smester project is designing buck converter controlled by sg3525. my sg3525 is correct for pwm generation but problem is that i want to use 20khz frequency and the circuit i designed has minimum frequency of 400khz . so question is that is how to generate...
pwm circuit of sg3525
hi to every one . please help me in understanding the following circuit,please....i am new in electronics and i am very interested in electronics..the circuit is
hi to every one , my question is that does there any need of driver for the gate of mosfet when using sg3525 for pwm. i am saying this because i generate pwm and i was driving a 1amp dc motor through mosfet and it was working fine without any driver.,so its realy no need of driver for mosfet ...
thank u very much deepone for ur response . but sir i have to use ka3525 to produce 60% duty cycle and 100khz frequency and feedback but here problem is that i have no idea of using this ic ka3525 to do these three jobs :( . can u help me in generating 60% duty cycle,100khz frequency and...
hi..
i have to design a switched mode car battery chager. i am new in electronics , this is my project ,so please, please and please any body help me in my project ..
i have to design 300watt or above than 300 watt charger ...please give me a complete block diagram of this circuit (i will be...
