Basic Circuit Design - Synced PWM

"The length of the output pulse should be proportional to the frequency. i.e. 10% and adjustable."- This is not obvious. Is this mean that "The higher the frequency of input sine signal, the longer the output pulse, thus the lower the output pulse."? I think that your project can be done by using comparator, frequency to voltage converter, so on...

Hello, I have this circuit ready with me. I used the circuit to trigger the photo-triac. Photo-triac can be replaced with the LED. I can give the simulation results also, so that you can verify that the circuit is working. You may message me for discussing more details.

hi sir i am an expert electrical engineer i can do it for you. please share the further details. i am waiting for your reply regards

I am an Electrical Engineer having specialization in Electronics and Control, working as Lab Engineer at FAST National University Pakistan, at Electrical Department. Now a days i am also doing my MS degree in Electrical Engineering with specialization in Control. I have conducted the labs for followings subjects, and also supervised Projects related to these subjects. 1. Control System Design & Modelling (Matlab & Simulink) 2. Digital Logic Design (Verilog, VHDL) 3. Digital System Design (Verilog, VHDL) 4. Computer organization & Assembly Language (8086 processor, 8051 controller) 5. Electric Machines 6. Circuit Analysis and Design etc. I assure you, if you assign your project to me, you surely gonna work with me in future.

I'm an Electrical Engineer in Communications and Electronics. I have experience in microcontrollers programming, including PIC and AVR. I have experience in designing electronic circuits for specific industry tasks. I hope I can help with this project Best regards

Circuit will be designed and schematic drawn, 1) The duty cycle proportional to input frequency -adjustable manually. 2) Trigger level for threshold adjustment (like oscilloscope) I just rephrased what I think is your requirement. The trick is to use a frequency to voltage converter and then use a simple voltage-PWM generator, the generator's clock is threshold synced by input waveform.

Hi. I am a professional Electronics Engineer having expertise in Circuit designing. I have done many of the projects same to your's and have their simulations too. I can provide you the work solution in some hours ( 0 Days ) Contact me i am waiting for you.

I recently finished my fourth year of undergraduate electrical engineering at Carleton U. I have 2+ years of experience in designing pulse-generating circuits with incoming sinusoidal signals as inputs. With more details as to what format the design is to be done on, I am confident I can complete it in no time.

Hello, I am a Hardware and Firmware Developer cum Schematic/PCB Designer, having 9+ years of experience. Expertise in Arduino, AVR, PIC, 8051 programming. PCB/Schematic design expertise in Proteus, Altium, Eagle, Orcad. Also having expertise in using Simulators like Proteus, Multisim, PSpice. So, I can simulate this project just in some hours. And if u want some changes in the result as per your specific requirement, it can be easily done. I already design the type of circuit u required. Thanks Sapna Surve

Respected sir, I am an electrical engineer , and i already did this project of SVPWM(space vector pulse width modulation) i hope you would give me a chance . i did simulation of SVPWM too. so may be i can help you

Hello, I am professional prototype engineer with 6 years experience in big automotive company. Looking forward to working with you!

I can make the diagram(circuit)its very easy,without the other components,its probably for controlling a motor.

Will need to know frequency range (max/min) and if the circuit must be input amplitude independent or not. If so, what amplitude range (max/min) does it operate over. Circuits that self-adjust (using feedback loops) to dynamically track changes in the input signal will inherently have a response time limitation. Having both a fast response time with also being able to cope with very low frequency inputs becomes a challenge and might better be done digitally. If the range of variation in input frequency and amplitude is not too huge (>= 3:1 ratio) and you can tolerate a fixed response time equal to roughly 10 cycles of your lowest input frequency, then an all analog circuit is a reasonable approach. If however, your range of variation on frequency is much wider or you demand very fast response time, then you become forced into using digital techniques forat least some of feedback control. Are you ok with this???
