Message: Hi audioguru,I have decided to build the circuit with CD4047 together with CD4001 and IRFZ44.
Message: Hi audioguru,you mention that the 12V feeding the ICs should have a 100ohm resistor in series and a 16V zener diode to ground at the ICs.
Message: Thanks audioguru, well i had troubleshooted the circuit many times but the configurations was correct. Message: The ground points of the entire circuit must be connected together or the circuit will not work. Message: Hi audioguru,I had managed to troubleshoot the circuit and for the cd4047 and MC14001BCP is used to replace cd4001 are both functioning properly. Message: Hi, in order to have a sine wave, a low pass filter must be integrated to the circuit so as to remove away the odd harmonics. Message: another thing is why is there a need for resistors to be present before the gates of the mosfets?
Message: Pin 10, 11 and 13 of the CD4047 and the outputs of the Cmos gates are a square-wave with a peak voltage of at least 12V and turn on the Mosfets perfectly. Message: quote:Originally posted by sympsydi'm bit confused with this waveforms, can u please epxlain? Message: salam i have made this circuit but the problem is same i got 106volts ac wheni apply 15 volts dc but i am using 2700u capacitor b4 inductor.
Message: The circuit that was posted in this thread 8 years ago uses a CD4001 Cmos logic IC powered from a 12V battery and it drives Mosfets that have no input current. Pulse Width Modulation Control, Uses: Motor Control, DC Dimmer, Electrolysis, Heating control.
Welcome to BAKATRONICS LLC, Manufacturer of Electronics and Supplies for the model railroader! That circuit is not a purely a square wave as the presence of inductor and capacitor act as a filter.
Hopefully, it i will be able to get the voltage and waveform that was required.Just to clarify something, the resistor value that was input to CD4047, can i use a potentiometer instead of fixed value so as i can adjust the frequency accordingly?
I obtained a constant DC output for the cd4047 at pin 13 instead of a square waveform(Clock pulse).
Anyway, i will check and update you again.By the way, are all ground pins of the cd4047, cd4001 and Mosfet ground at the same point meaning that isolation are not required??? I would like to know the purpose for the circuit on the top left hand corner, the zener, the cap and the resistor. So a different transformer is used.A high current filter to convert a 50Hz square-wave to a 50Hz sine-wave will be huge and will have such a high resistance that very low power will be at its output. It might also eat your tiny motor.Make a 5W power amplifier with a stepup transformer and feed it a sine-wave. Can I using SG3526 to generate a PWM instead of microcontroller?I have never seen an inverter because my electricity is reliable.

A change in voltage on the primary will cause all secondary coils to produce a derivative voltage.
Its output voltage is only 5V so the output transistors or Mosfets barely turn on and the output power from the inverter will be very low.
We will delete it soon, if we are involved in the problems of article content ,copyright or other problems.
Is it the same connection that you mention for the zener diode and resistor?if yes, but the diagram uses 47ohm as a resistor and not 100ohm so which one do i use? But i managed to get a square waveform at the pin 10 and 11 which both are inverted of one another at a frequency of 50Hz. Then it uses a microcontroller to make pulse-width-modulation at 50Hz or 60Hz and feeds an H-bridge with high voltage switching Mosfets that produce the sine-wave with many steps in it, then two small high frequency filters.
An ordinary AC voltmeter will not measure the peak voltage of a square-wave since they are made to measure a sine-wave which is very different.The no load draw from the battery is only 12W which is low. If you single out a 10% PWM duty cycle you will see that for 10% of a PWM cycle the primary coil is being energized - current is increasing in the primary so voltage is being induced in all secondaries. The modulated high frequency drives the Mosfet H-bridge and an LC filters out the high frequency switching carrier frequency.
The resistor, zener diode and capacitor prevent their destruction and should always be used in that circuit.The CD4001 is feeding the gates of Mosfets that use no current so the CD4001 should be cold and not be hot.

Now mine concerned is that how am i able to produce a 230Vrms output without any load connected at the output of transformer.
Also did you understand that the signal from your '555 must also have another signal 180 out of phase with it (two signals).
From my understanding, the dc capacitor will charge and discharge and thus able to make signal alternating. You have an ICM7555 which is a low current Cmos 555 that has an output current of only a few milli-amps with a high voltage loss. I think it has something to do with there tendancy toward non-linearity, so they are apt to produce more energy at various harmonics & spurious emittions. According to the electronic forum, i had read that there were 2 capacitors required for non-polarities. I had changed a new cd4047 IC chip but the results are the same, do you know what are the reasons behind it?Thank you for your precious time. The capacitor is needed for any electronic circuit.All Mosfet circuits use a low value resistor in series with each gate close to the Mosfet (some use a ferrite bead) to prevent the Mosfet from oscillating at a VHF or UHF frequency.
The quality of the transformer affects how much is the battery current without a load.Now you say the output is low.
If the capacitor and inductor do not have any internal resistance then a 5V mains transformer will produce a square-wave output that increases when the load current decreases.

If you put a near 100% duty cycle on the primary, each cycle should only just reach the saturation point of the core material used in the transformer - for maximum efficiency. The cycle length of a single PWM cycle should be several times smaller in order to reproduce the modulating wave form in PWM. Maybe the voltage regulator, cD4001 and also the Mosfets are destroyed because you did not use the resistor, zener diode and capacitor.
I hope that you are able to guide me on that schematics drawing on which part and how to modify it.As i was thinking whether can i change my rating of my transformer or can i modify the circuit in such that it will function as centre tapped transformer.
If you don't use push-pull then you only need one transistor or you can parallel two of them but not like that. The TIP41 and TIP42 transistors need a base current of hundreds of milli-amps to switch 3A to produce 36VA.
It might be made with a cheating turns ratio to make up for a low output voltage when it is used for a step-down transformer. But according to the diagram, only the 220nF capacitor is required for the AC part but not for the 0.1uF capacitor which must have polarities. If so, If I generate high frequency PWM to switch, how can I use a lowpass filter to change back to 50HZ output? The filter is designed to oscilate at 50Hz and will not pass the PWM frequency of which should be several times higher than the 50Hz modulating signal. Maybe it is what audioguru had stated about the losses.If i need to use centre tapped tranformer, i need to use 2 same npn transistors and not npn with pnp.
A current is needed at its input to quickly charge and discharge its high input capacitance. Did you measure the voltage with a True-RMS voltmeter because an ordinary voltmeter cannot measure these digital signals.
I have posted a few that work in this forum.A CD4047 is an oscillator IC that uses one resistor and one capacitor. High frequency transformer is very difficult to find, can rewind it by myself by using toroidal core?I don't know where you will find a ferrite core that does not saturate with the high current in its coil.
So even though you have pulsed a constant voltage across the primary, the primary DC is increasing from 0 Amps over time which in so doing induces a voltage in all secondary coils.
It has two opposing square-wave outputs to drive two Mosfets that drive a center-tapped transformer.
Just like everything in the universe, a change of some sort is needed to do any kind of action.
