Use the Sinewave Generators to generate up to 32 independent sinusoidal signals on the FPGA.  These signals can be mapped directly to Analog Output channels or to voltage and current Sources in the circuit model. 

Sinewave Generators Section Channels

In the System Explorer window configuration tree, expand the Power Electronics Add-On custom device, then Circuit Model >> Sinewave Generators to display the following subsections and custom device channels.  Assign values to the channels to configure the Sinewave Generators.

Default Value

Description


Auto Synchronize

Input
0 (False)
  • False: Normal operation
  • True: Synchronizes all Frequency Engines to each other to prevent phase drift but  if the amplitude, phase, or offset of the generator is changed it can cause undesired outputs.  

Reset

Input
0 (False)
  • False:  Normal operation
  • True:  Resets all Frequency Engines to 0 degrees
SWG X

Channel NameType

Units

Default Value

Description


AmplitudeInputVolts0V

Amplitude of the generated sinewave. The peak-to-peak value will be twice the amplitude.

Frequency EngineInput
0

Index of the Frequency Engine X used to generate the sinewave.

Setting a value of 2 will connect Frequency Engine 2 to the sinewave generator. Assign the same Frequency Engine X index to multiple sinewave generators to ensure that they stay phase locked in time.

OffsetInputVolts0VDC offset of the generated sinewave.
PhaseInputDegrees

Phase offset of the generated sinewave relative to the other sinewaves using the same frequency engine.
