I will try to help but as others have said, your spec is still unclear. ? X means a minimum size width for n and p channel transistor width for the transistors inside the inverter . ? 8X means n and p ch widths are 8 times that of 1X inverter. ? D<9:0> means data lines; these are digital outputs that change after the
Hello to all. I am building a 1000w pure sine wave inverter. It has a 12V to 320V converter made with an SG3525 controller and BD139/BD140 at the output as a driver, 2 ETD39 ferrite core, each of them driven by 4 IRF3205 fets. The secundary winding of the transformers is in series ( they are supouse to be 160V each) so after this stage th

In the 70's and 80's there was a lot of work done on how to turn off inverter grade SCR's with forced commutation by employing large-ish charged capacitors that are connected across the SCR's to force a reverse current slightly greater than the load current to give a small net reverse current in the SCR to ensure forced turn off, the problem then
Before you can design any project, you must stop and think about , then write down a list of requirements. Never start without this 1st critical step. Surge current max (startup and fault load) including ; protection required , Environmental limits, power, regulation accuracy, user inputs and outputs. Then if not already should examine specs of e

Depending on the type of load expected on output, and the allowable cost incresing, a fast circuit breaker would be a reliable option. By the way, additionaly are you already adopting some overcurrent loopback control on inverter driver circuit ? +++
I presume you have an idea about the block diagram of the inverter. To use the ferrite transformer for battery charging, you need to feed the high voltage winding of the transformer with a 50 kHz AC voltage. How do you chop the mains voltage (probably after rectifying it)?

hey guys, I'm an undergrad in software engineering and I'm doing my final year project. I'm trying to power up a monitor and a Beaglebone Black from the car. I have used a 100W inverter for the monitor and a LM2596 regulator for the BBB. And the LM2596 is a switch mode power regulator. Check diagram. 104981 But I d
The question can't be answered from the user manual. I think there's a good chance that the monitor has a single +12V internal supply, but it might e.g. use a different voltage for the backlight inverter. You'll either consult a circuit diagram/service manual or find out yourself. In any case, many other LCD displays have an external 12V supply.
Google for "active front end rectifier" or "active front end inverter"
This is the diode they were talking about. Refer to the schematic diagram of that inverter... 8ETU04

am working with a inverter project.... it's output varies from 5v to 15v can i get a constant voltage of 12V ,, can anybody please post the circuit diagram??? :roll:
This is a hazardous thing to build due to high voltages and parts that can explode if it is not built correctly with suitable parts. This is what I think from looking at the circuit diagram, might not be competely correct. It is a big feedback loop. U1 is a microcontroller running software. The software creates a pulse width modulated outp

I have used this inverter with Hittite attenuators, without any problem. The diagram shows, however, a 7404 while you write about 7414 and CD4053.If their OUTPUT is TTL, then any of them should also work. The 7404 is simply powered by 0/+5V but "buried" under zero volts. The input 5V Zener is important as it allows this level shift.
