Interpolated Firing Pulses

 

 

 

Description

This component returns the firing pulse and the Interpolated Time Tag required for an interpolated turn-ON (or turn-OFF) of thyristors, IGBTs and GTOs, in the form of a two-element array.  The first output element is a 0 or 1 and represents the actual gate control pulse.  The second is information regarding the interpolated switching time.

 

The output is based on a comparison of high (H) and low (L) input signals. The low L input is normally a firing angle (a) order and the high H input is from a phase-locked oscillator or equivalent.  The Interpolated Firing Pulses component can be set to produce timed firing pulses for:

NOTE:  If a GTO or IGBT is used, then an input signal comparison is provided for the OFF signal as well.

 Name for Identification

 

Text

 

Optional text parameter for identification of the component.

         

 Thyristor or GTO?

 

Choice

 

Select Thyristor or GTO (IGBT).  

 

This parameter determines the format of the output control signal depending on whether the device being controlled is built with thyristors or GTOs.

 

 

 

 

 

Number of Pulses

 

Choice

 

Select One or Six.

 

Select One if a single thyristor or GTO is to be controlled.  Select six to provide output for a six-pulse, thyristor or GTO bridge.

 

 

 

 

 

Add Block/Deblock Signal?

 

Choice

 

Select Yes or No.  

 

If Yes is selected, the component will expect an additional external signal for blocking control, where:

  • 0 = Block

  • 1 = De-Block

 

 

 

 

 

Format of Pulse, Time Output:

 

Choice

 

Select To Individual Devices (6 outputs of dimension 2) or To Six Pulse Thyristor Group (2 outputs of dimension 6).

 

Select the first option to supply a custom built 6-pulse bridge with control signals.  Select the latter option if controlling the 6-Pulse Bridge component.  Note that this option is only enabled if Thyristor or GTO? | Thyristor and Number of Pulses | Six is selected.  See Setting Up Firing Control.

 

 

 

 

 

Band Limit Proximity Correction

 

Choice

 

Select Disarmed or Armed (must indicate H input band limits).  See Setting Up Firing Control.
