AI Thread Summary
A user is seeking assistance in designing a simple UPS circuit using a full bridge IGBT or MOSfet with an output of 220/240V at 50Hz. They specifically request a driver circuit for the IGBT or MOSfet and inquire about using a DC power supply connected to an inverter to achieve a sine wave output. The discussion highlights the importance of power output and output type, as well as considerations for measuring total harmonic distortion (THD) of the output wave. Suggestions include using a meter for distortion measurement or performing a Fast Fourier Transform (FFT) on the output. The conversation emphasizes practical aspects of the project, including potential alternatives to building the circuit.

request...with UPS cct

can anybody please help me...
i want a simple UPS cct using full bridge IGBT or Mosfet with output 220/240v 50hz
i need the driver cct for the IGBT or Mosfet as well...please...

Welcome to PF.

Critical factors are the power output and output type (square wave, modified sine wave, sine wave).

Have you considered a computer or autoparts store?
Probably cheaper than building your own.
 
actually this is my eng. project. can i do it just by using dc power supply and connected it to an inverter?
so that i can get the desired output (sine wave) and how can i measure the (THD) total harmonic distortion of the output wave?
 
Well, this is your project.
What would be the specifications for a DC power supply to run an inverter?
You could use a meter to measure distortion or sample the output and run a FFT on it.
 

Thread '3-terminal device external modeling'

Very basic question. Consider a 3-terminal device with terminals say A,B,C. Kirchhoff Current Law (KCL) and Kirchhoff Voltage Law (KVL) establish two relationships between the 3 currents entering the terminals and the 3 terminal's voltage pairs respectively. So we have 2 equations in 6 unknowns. To proceed further we need two more (independent) equations in order to solve the circuit the 3-terminal device is connected to (basically one treats such a device as an unbalanced two-port...

Thread 'Question about the voltage between two charged capacitors'

suppose you have two capacitors with a 0.1 Farad value and 12 VDC rating. label these as A and B. label the terminals of each as 1 and 2. you also have a voltmeter with a 40 volt linear range for DC. you also have a 9 volt DC power supply fed by mains. you charge each capacitor to 9 volts with terminal 1 being - (negative) and terminal 2 being + (positive). you connect the voltmeter to terminal A2 and to terminal B1. does it read any voltage? can - of one capacitor discharge + of the...

Thread 'Weird near-field phenomenon I get in my EM simulation'

Thread 'Weird near-field phenomenon I get in my EM simulation'

I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...
