Hey Mtwieg, Thanks for replying :) That is true!!

Hey dick_freebird, That was right...
Hello,
I'm working on IC MAX 16833 chip as an LED driver in LTspice simulation.
I was facing an error saying "Shorted voltage source: u1:vg2"
u1 is the pin name and there are no other pins like vg2 on the chip or anywhere on the board.
But the circuit was a weel established one already and all...
Hi Klaus,
Yes it is working differently under load. I'm working on some concepts about filters now. I will sure update the design. Please let me know if you know any better links regarding this concept.
I appreciate your help.

Hi,
The capacitors after the H bridge are to convert the PWM squares into a sine wave. The inductor present above along with capacitor should work as a filter that gives a better sine wave. The resistors are used just for the discharge path. In simulation, that combination is giving a perfect...
I actually used some experimentally. Simulation works absolutely well. But, when comes to the practical scenario,it didn't work. I was thinking the use of my non polarized caps after the H bridge are causing some short circuit and providing a reverse current. This indeed created a spark and...
@betwixt, Yea i'm going to order ir2110 gate driver and replace it. I will connect it according to the data sheet.
Yes you are right. I got that part of getting DC from AC.
Yes. I actually require a voltage of 120 VAC with 2 amps of current at the final output. I'm attaching a full circuit now. please have a look at it.
Thank you
Hi, I tried this circuit both in simulation and in practical manner. Below i used a gate driver IR2112 to drive the gates of the two mosfets, which boosts my PWM 5V amplitude signal to PWM 15V. My goal is to get equal distribution of voltage of the DC rail input applied to the drain of Q1 at the...

Hi, Could you please explain, which of them would cause fire? I have got all the components and got ready to work on the hardware part, since the simulation worked perfectly well.
Please explain what changes I can make to the circuit to work under safe circumstances. Any help is...
Okay. If I don't use 10K resistor, I'm afraid that the time constant for filtering ac to dc might get affected, which may in turn cause ripples in output DC.
Could you suggest any other value to the resistor? And, would there be any serious issue with zeners? They are the key components which...
sorry , I was wrong. My total circuit is an AC-AC Converter. This is just the first part taking the universal input and regulating it to 240 V constant DC.
The other part of the circuit converts this fixed DC to 120 V AC, with 2 amps. My load is of 240 W LED driver. Below i attached the...
