Programmable Voltage Source

Single-phase AC voltage source with programmable amplitude, frequency, phase shift and DC offset.

programmable voltage source

Description

The Programmable Voltage Source unit simulates a single-phase AC voltage source with programmable amplitude, frequency, phase shift and DC offset. Select external mode to set these values using M, F, Phi and DC input signals. Higher harmonics and noise can also be included in the voltage source.

Limitations

Modelling with higher harmonics included slows down the simulation. If you include harmonics, choose the interval between calculation steps so that harmonics are generated only at the frequencies of interest and not above.

Modelling with noise enabled slows down the simulation. If you include noise, select the interval between calculation steps so that noise is generated only at the frequencies of interest and not above.
