Abstract

The synchronization devices for the network controlled power valve converters, based on integrate sweep converters with frequency-width-pulse modulation (SC) were reviewed.

A block diagrams of the system, a time diagrams of the signals and synchronization conditions of SC switching frequency by the external bipolar rectangular and harmonic signals were shown. As an example of a three phase reverse thyristor converter of DC the function block diagrams of cross and interval-code synchronizations was shown.

A functional diagram of SC, the main calculated proportions and the recommendations for choosing the parameters were given.

This article may be interesting for engineers and technical employees, who work with the design, debugging and exploitation the power converter equipment.

Keywords

Synchronization device, valve converter, sweeping converter, interval-code synchronization, cross synchronization, phase shifting device, decoder, pulse distributor.
