Pspice simulation of my 3 phase inverter

[maclea98]

Trying to preform AC sweep on my pspice 3 phase inverter but simulation doesnt apear there are no errors could someone please help . I aslo need to keep transfering my traingular wave creator from previous try doesnt save correctly .
thanks people

ok so now i have out put of 100v is this the rms value because i cant get the sin wave on the simulation , would be great help

Hello,

Can you post a schematic in the form of a picture instead?

 

[maclea98]

thanks i have now made it so it can be veiwed , kinda embarrasing Im now getting no fs value for v1 v2 and v3 .
ive uploaded picture and working schematic thanks for your time

Hello again,

What simulator are you using? Do you need a ground for the lower transistors and the battery?

 

[maclea98]

yeah i need a ground oops , pspice student 9.1

Sorry about that , now the output is 100V and the simulation result shows just flat 100v is this rms or DC and my design is wrong

Hi,

Your output should be switching if the drive is correct. Did you check the drive signals to see if they are correct?
What are those blocks with outputs labeled "GA2" etc.?

 

[maclea98]

The blocks are simulating output from optocouplers

well i think it works if it blows up tommoro its all good XD
