Inverter Voltage Formula
The following formula is used to calculate the Inverter Voltage.
VI = Vdc * dm
- Where VI is the Inverter Voltage (volts)
- Vdc is the DC bus voltage (volts)
- dm is the difference in modulation indices
How to Calculate Inverter Voltage?
The following two example problems outline how to calculate the Inverter Voltage.
Example Problem #1:
- First, determine the DC bus voltage (volts). In this example, the DC bus voltage (volts) is measured to be 95.
- Next, determine the difference in modulation indices. For this problem, the difference in modulation indices is calculated to be .45.
- Finally, calculate the Inverter Voltage using the formula above:
VI = Vdc * dm
Inserting the values from above and solving the equation with the imputed values gives:
VI = 95 * .45 = 42.75 (volts)
Example Problem #2:
Using the same process as example problem 1, we first define the variables outlined by the formula. In this case, the values are:
DC bus voltage (volts) = 42
difference in modulation indices = .75
Entering these values into the formula or calculator above gives us::
VI = 42 * .75 = 31.5 (volts)
