Resource Overview

Single-phase thyristor rectifier circuit where AC power supply, after voltage reduction through a rectifier, is fed into the rectification circuit. A pulse generator produces synchronized pulses to control thyristor conduction. Since six-pulse generation is implemented, two pulse channels with 180-degree phase difference must be selected for thyristor triggering control. Code implementation typically involves phase-locked loop synchronization and precise pulse timing algorithms.

Detailed Documentation

This circuit utilizes a single-phase thyristor rectifier to convert AC power supply voltage into DC voltage. After voltage reduction through the rectifier, the power is delivered to the rectification circuit. We employ a pulse generator to produce synchronized pulses for controlling thyristor conduction. Notably, the system implements six-pulse generation, requiring the selection of two pulse channels with 180-degree phase difference for precise thyristor triggering control. In programming implementations, this typically involves using timer interrupts or PWM modules to generate accurately phased trigger pulses, often incorporating zero-crossing detection for synchronization with the AC waveform. The control algorithm must maintain strict phase relationships between pulse channels to ensure proper rectifier operation.
