The circuit comprises a voltage source loop which is used for controlling the working state of electronic elements in the voltage source loop according to the type of a sample valve in an accessed sample and providing a test voltage for the sample, and current source loops which are used for controlling the working state of electronic elements in the current source loops according to the type of the sample valve in the accessed sample and providing a test current for the sample, wherein the sample valve may be a one-way thyristor valve or a two-way thyristor valve.

Description

technical field [0001] The invention relates to the field of power electronics, in particular to a thyristor synthesis test circuit and method. Background technique [0002] Thyristor valves include one-way valves and two-way valves. Usually the check valve works in the active circuit to realize power transmission. Two-way valves are usually used for dead supply compensation. The two-way valve can realize two-way conduction under the action of sinusoidal voltage, while the one-way valve can only realize one-way conduction. [0003] High Voltage Direct Current Transmission (HVDC) valves are typical check valves. Static Var Compensator (SVC) valve is a typical two-way valve. [0004] In order to ensure the normal operation of the working circuit of the thyristor valve, it is necessary to perform a performance test on the thyristor valve before putting the thyristor valve into use. However, in the actual implementation, it was found that the circuit used for the thyristor ...
