Three Phase Controlled Rectifier

Product Description

Nvis 7202 Three Phase Controlled Rectifier is an important product in the field of Power Electronic Laboratory. This three phase controlled rectifier is designed to demonstrate the fundamental concepts and operational working of a Three Phase Low Voltage controlled rectifier using various load configurations. Rectification is the process to convert an alternating current into direct current. The three phase full wave controlled rectifier configuration helps students understand controlled rectification and the operation of power electronic circuits.

Nvis 7202 is equipped with an SCR firing control circuit that helps study the operating characteristics and performance of three phase rectifiers.  It helps students study the operation of a three phase fully controlled rectifier and understand how controlled firing pulses affect the rectifier output.

It helps students to know how to generate firing pulses for Three Phase Rectifiers using a ramp comparator scheme. It also incorporates Nvis 7201, which has two identical Three Phase Low Voltage Power Supplies that provide balanced 18V (line-to-neutral) and 28V (line-to-line) voltages to operate the power and control circuits.Students can conduct experiments in a sequential manner with utmost safety.

The three phase full controlled rectifier setup provides a practical way to study controlled rectification with different loads. The product also supports configurations that help students understand the difference between a three phase half controlled rectifier, semi converter, and fully controlled rectifier.
