DGSK20-018A, belonging to the category of diodes, is a three-phase thyristor module, which offers high performance and stable operation. This product is especially suitable for applications in fields involving high current and high voltage, like charging system for electric vehicles or power supply for UPS.

The working principle of DGSK20-018A can be explained through the figure below. A three-phase network is composed of three single-phase sinusoidal sources with a phase displacement of 120°. There are six thyristor connected to the network, three of which are connected to the positive half of the sinusoidal wave and the other three to the negative half. During the positive half-cycle of a sinusoidal wave, one positive thyristor is opened and the three negative thyristors are kept closed. Similarly, during the negative half-cycle, one negative thyristor is opened and the three positive thyristors are kept closed. Thus, the result is a controlled three-phase current.

The typical applications of DGSK20-018A include electric vehicle charging systems, electric power transmission lines, power supplies for electric vehicles, reactive power compensation, welding machines, and uninterruptible power supplies (UPS). Additionally, DGSK20-018A is also suitable for applications involving arc furnace electric drive, motor speed control, and AC servo motor systems.

The design of DGSK20-018A incorporates an advanced heat dissipation system, to ensure its stable operation under high temperature and over voltage conditions. Moreover, the connection ports of DGSK20-018A are separated from the package to reduce thermal decomposition and offer improved safety. Additionally, its connection ports are configured on the same side, reducing the amount of wiring, and thus saving time and effort in the installation.

In order to protect the surrounding environment, the design of the DGSK20-018A incorporates several standard features, such as over-temperature protection, voltage transient suppression, and current limiting protection. Moreover, the presence of IGBT (Insulated Gate Bipolar Transistor) and EMC (Electro Magnetic Compatibility), guarantees increased safety and reliability of this product. As a result, DGSK20-018A satisfies the necessary regulatory requirements, and thus, can be used in all types of applications.

In short, DGSK20-018A, an innovative thyristor module with advanced features, offers high performance and reliable operation in many applications, like electric vehicle charging system, power lines, reactive power compensation, welding machine, uninterruptible power supply, arc furnace electric drive, motor speed control, and AC servo motor systems.
