Thyristors and SCRs (silicon controlled rectifiers) are used in many applications for the switching of power and voltage. The devices have implementations in slow-switching or high-power applications. VS-VSKL136/16PBF, specifically, are often used for welding applications that typically have steep switching edge susceptibility. The design and components of the VS-VSKL136/16PBF module make it well-suited for such applications.A module like the VS-VSKL136/16PBF is a power unit that typically contains several thyristors connected together in various configurations to do specific functions. It is designed to work as an all-in-one power-control solution for various applications. The number of thyristors in the module can range from one or two to twelve, depending on the specific module.The VS-VSKL136/16PBF module contains a total of sixteen thyristors in a 16PBF configuration. This is an acronym for “eighteen-phase bridge formation”, which is a type of electrical configuration that uses eighteen thyristors in a bridge formation. This arrangement is useful as it allows the thyristors to be placed in series or parallel as needed for the application at hand.The main components of the VS-VSKL136/16PBF module include a voltage divider, a starter, a protection diode, and thyristors. The voltage divider is used to reduce the voltage between the anode and cathode of the thyristors. The starter is used to turn the thyristors on and off at predetermined times. The protection diode, also called a “flyback diode”, is used to protect the thyristors from current flow in the opposite direction. Finally, the thyristors themselves are used to control the switching of the power and voltage.The working principle behind the VS-VSKL136/16PBF module is relatively simple. When the starter is turned on, it provides a voltage which causes current to flow through the voltage divider. This causes a voltage across the thyristors, which turn them on. The thyristors then switch the power and voltage in the direction they are designed for. When the starter is turned off, the voltage divider stops providing current and the thyristors turn off.In terms of application fields, the VS-VSKL136/16PBF module is ideal for welding applications. Its steep switching edge susceptibility makes it well-suited for precisely controlling the welding arc. It can also be used for similar applications such as induction heating, which requires a precision switching of power.In conclusion, VS-VSKL136/16PBF modules are a powerful and efficient all-in-one solution for many switching and power control applications. They are well-suited for welding applications due to their steep switching edge susceptibility. The modules contain a voltage divider, starter, protection diode, and thyristors, with the thyristors being responsible for switching the power and voltage.
