6-Pulse Generator

Purpose

Generate firing pulses for 3-phase thyristor rectifier

Library

Control / Modulators

Description

../../_images/6pulsegenerator.svg

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 \(\varphi\) (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.
