Single Phase Inverter using Simulink

single phase inverter

Hi everyone....I'm studying in electrical engineering..I'would like to study about inverter..especially using simulation in simulink...Can anyone give me an example about designing single phase inverter in simulink?

Hi kristanto !

Many useful Matlab and Simulink demos - examples you will find on

Mathworks web-page :

Good luck .

It is very good example for H-bridge inverter by using matlab simulink.

simulation inverter with simulink

ok so you simulate inverter with simulink?

but no simulator can really simulate a large inverter circuit.

cuzz it takes too long.

so you have to make up blocks of math equations and simulate these.

but how do you know whether or not these blocks are true to your real life inverter?

you dont...unless you do loads and loads of verification testing....and then if you modify your inverter a bit, you have to re-verify all over again.

and how did you do the expression for the feedback loop....did you use state space or the PWM switch loop model........?

...why do you want to simulate?

who is going to take all the time to look at your results and verify that your simulation is true to the real thing.

My sales manager says simulation is just computer games for engineers.....and maybe he's right....i've never known a company who really worked off simulations.....and usually the simulation only gets finalised after the product has gone to market and is on the shelves.

mini- 5minute simulations of subcircuits are good to see if you made a mistake wiring it up.....but simulating a switcher?....if it was worth it then surely more places would do it

good advice thank you.

but how do you know whether or not these blocks are true to your real life inverter?

you know its not true to real life because you are using simulink.

simulink is good for architecture studies and controller design (top level) only. once you're happy with that you move to PSpice to detailed design and analysis (part stress, power dissipation, design assurance etc).

then build the thing.

@ eem2am:

You sales manager knows how to play games not to develop the games. Simulation is not a complete test of any product/software but it helps to debug and visualize desired output.

oh, and for the record i did simulate a 50kW 3-phase inverter driving a BLDC motor with speed control and current regulator with 20khz switching and high dynamic performance ALL IN PSPICE. it takes a few minutes to simulate a few hundred miliseconds.. so you can only simulate certain conditions.. but it can be done.

i have also used simulink with DSpace to simulate a controller while real hardware (the same 50kW inverter & motor simulated in pspice which was built as a prototype) was on the bench and powered and really spinning the motor.

i think that's about as close as it gets with simulation with the technology existing today. i thought it was a very good experience and it was actually quite useful.
