Thyristors - SCRs - Modules are vital components in many industrial and commercial applications. Among these, VSKH500-14 is one of the most commonly used, so it is essential to understand its application field and how it works.The VSKH500-14 is a thyristor SCR module that is used principally in applications using electricity as a source of power. This worldwide used module is most likely to be found in motor speed controls, industrial heat/light controllers, and power rectifiers.An SCR is a three-terminal, gate-controlled semiconductor device, formed of a thyristor, a diode, and a gate. The module VSKH500-14 uses a high rated current of 500 Ampere- and a voltage rating of 1400V. It is also equipped with an on-state non-repetitive surge current of 1000A for two cycles.In order for the VSKH500-14 to provide the desired application result, power must be applied to the three terminals, connected to the module. The first terminal, also known as the anode, and the second terminal, known as the cathode, are connected to an AC bridge network, made of two controlled switches and two diodes, giving the possibility of connecting either three-phase or single power options. The third terminal, also known as the gate terminal, is connected to a control system, usually external to the module such as a signal generator, or an external timing system.When powered, the gate signal must be applied to the VSKH500-14 terminal, in order to be effective in controlling current and voltage. When the gate pulses are stationary, the SCR module will not be conducting current, and it works as an open switch. During the time when the gate pulses present, the SCR is forward-biased, and electricity will flow between the anode and the cathode terminals. This action can be exchanged a few times, followed by the deactivation of the electrical flow when the gate pulses are off.Once the current controlling is understood, further enriching the performance of the VSKH500-14 SCR module is possible by both series or parallel connecting of modules. This is helpful when a circuit or machine requires higher current and voltage handling especially in high-power AC applications.The VSKH500-14 SCR module is an essential component for many applications because it is reliable, repeatable, and very cost effective. Its popularity is highlighted by the widespread use and dependability present in many commercial and industrial factory- and machine-powered applications. The clear understanding of the device, in terms of application field and working principle, amplifies its capabilities in many industries.
