What is the principle of High-Power Electrolytic Rectifier Power Supply?
May 12, 2017

The double star rectifying circuit is used as the main circuit. The high voltage 33KV directly steps down through an on-load voltage regulation rectifier transformer and is subject to 12-phase rectification by thyristor into DC current and voltage (current 0-16.2KA; voltage 0-230V) required for the ionic exchange membrane cell. The rectifier outputs the anode of the direct current and the rectifier transformer makes star-point output of the DC cathode.

Each loop is composed of 3 thyristor components in parallel and receives the pulse signal from the trigger control loop through the pulse distributor connected with the gate pole, so that the DC output current and voltage meet the process requirements.

The incoming line terminal at the valve side of the rectifier transformer to the rectifier cabinet is provided with opening and closing overvoltage absorption circuits. Each rectifier arm is centrally provided with commutating overvoltage absorption circuit for internal short-circuit isolation protection with the fast acting fuse connected with the element in series.
