6-Pulse Generator

Purpose

Generate firing pulses for a three-phase thyristor converter.

Library

Control / Modulators

Description

pict

This block generates the pulses used to fire the thyristors of a 6-pulse rectifier or inverter. The inputs of the block are a logical enable signal, a ramp signal φ   (produced e.g. by a PLL), and the firing angle alpha.

If the "Double pulses" option is selected, each thyristor receives two pulses: one when the firing angle is reached, and a second, when the next thyristor is fired.

Parameters

Pulse width
The width of the firing pulses in radians with respect to one period of fundamental frequency.
Pulse type
"Double pulses" enables a second firing pulse for each thyristor.
