Thyristor Work Performance Quick TestCircuit

Description: Connect the diode VD under test to sockets X1 and X2. A stabilized power supply applies reverse breakdown voltage to VD, allowing the stabilized voltage value Uz to be read from voltage meter V. The stable operating current value can be monitored from the milliammeter mA that is connected in the circuit. The reading on the milliammeter will vary with the regulation of the circuit.

The circuit setup features a stabilized power supply that is crucial for accurately testing the diode's reverse breakdown characteristics. When the diode VD is connected to sockets X1 and X2, the stabilized power supply applies a controlled reverse voltage across the diode. This setup ensures that the voltage remains constant, allowing for precise measurements of the voltage and current.

The voltage meter V is used to measure the stabilized voltage value Uz across the diode. This measurement is critical for determining the reverse breakdown voltage of the diode, which is the point at which the diode begins to conduct in the reverse direction. The voltage meter should be capable of displaying precise voltage readings to facilitate accurate testing.

The milliammeter mA is integrated into the circuit to monitor the current flowing through the diode during the breakdown test. As the reverse voltage increases, the current reading on the milliammeter will change, providing essential data on the diode's behavior under reverse bias conditions. It is important for the milliammeter to have a suitable range to capture the expected current values without saturating.

This testing arrangement allows for the evaluation of the diode's performance characteristics, including its breakdown voltage and current handling capabilities. Proper calibration of the voltage source and measuring instruments is essential to ensure reliable results. Additionally, safety precautions should be observed when working with reverse breakdown voltages to prevent damage to the components and ensure safe operation.Plug the diode VD under test into sockets X1 and X2. Stabilized power supply adds reverse breakdown voltage to VD and the stabilized voltage value Uz can be read from voltage meter V, and the stable-working current value can be read from the milliammeter mA which is cascaded in the circuit.
