## What is the output line voltage of a 3 phase?

The formula is volts times the square root of 3, which happens to be rounded off to 1.732. For 2 lines each carrying 120 volts, the calculation for this is 120 volts times 1.732, and the result is rounded up to 208 volts. That’s why we call it a 208 volt three-phase circuit, or a 208 volt 3 phase line.

## How can the AC voltage at the output of a three phase PWM inverter be varied?

The output voltage of the inverter can be modified by changing the DC-link voltage amplitude or by changing the modulation index of the inverter by control circuit.

## How do you calculate voltage output?

The current flowing out of the power supply is just the voltage (5 volts) divided by total resistance, I=V/R, so: I=5R+RLED.

## What is the purpose of 3 phase voltage source inverter?

Single phase VSI is used for low power applications and three phase VSI is used for medium to high power applications. The main purpose of these topologies is to provide a three phase voltage source where the amplitude, phase and frequency of the voltage should always be controllable.
