Thyristors - SCRs - Modules

VS-VSKH91/08 is a four quadrant ac/dc thyristor firing module. It is used to control four quadrant power conversion systems. It consists of two high power thyristors, two temperature sensors and two trigger circuits.

The four phases of the module are DC, Positive Quadrant, Negative Quadrant and Zero Cross. The module works like a static switch that can be used to control the four quadrant power conversion systems. It allows for efficient power switching in both directions.

The module has a high power rating of 10000A and a peak voltage of 800V. The module has a wide operating temperature range of -55°C to +85°C. The module also has a high frequency of 210kHz.

The main purpose of the VS-VSKH91/08 is to control the four quadrant power conversion systems. It can be used to control the power flow, voltage and current in all four quadrants. It is also used for motor control, power factor correction and variable speed drive applications. The module can be used to control a variety of applications, such as Solar inverters, UPS systems, servo drives, welding machines and electric vehicle charging systems.

The VS-VSKH91/08 has a continuous current rating of 10,000A and a peak current rating of 16,000A. It has a peak forward voltage drop of 2.5V and a holding current of 10 A. It has a gate triggering voltage of 3V and a gate triggering current of 150mA. The module has a turn on loss of 1.5m and a turn-off loss of 4m. The module also has a turn-off time of 5.5µs and a reverse recovery time of 100µs.

The working principle of the VS-VSKH91/08 is based on the thyristor’s bi-directional behavior. A signal is applied to the module’s trigger circuit, which then causes the thyristors to switch on in the correct quadrant. This allows the module to control the power flow, voltage and current in the desired direction. The module also has temperature sensors that detect changes in temperature and the trigger circuits will deactivate the thyristors if the temperature exceeds a certain level.

In conclusion, the VS-VSKH91/08 is a four quadrant ac/dc thyristor firing module. It is used to control four quadrant power conversion systems. It has a high power rating of 10000A and a peak voltage of 800V. It has a wide operating temperature range of -55°C to +85°C. The main purpose of the module is to control the four quadrant power conversion systems. It can be used for motor control, power factor correction and variable speed drive applications. The working principle of the module is based on the thyristor’s bi-directional behavior.
