216VC624: Product OverviewThe 216VC624 is a high-power thyristor (silicon controlled rectifier) module from ABB’s power semiconductor portfolio, designed for demanding applications in high-voltage power electronics. This device serves as a critical switching component in voltage source converters (VSCs) and other power conversion systems used in HVDC transmission, static VAR compensators (SVCs), and large industrial drives. Its primary function is to perform high-speed switching of electrical power, enabling precise control over voltage, current, and power flow in high-power conversion systems.The module utilizes a press-pack housing that allows for double-sided cooling, which is essential for efficient thermal management at high power levels. The housing is designed to be pressed between heat sinks in a stack configuration, enabling multiple devices to be connected in series to achieve the required system voltage ratings. This construction is inherently more reliable for series operation compared to standard baseplate modules, as it fails to a short circuit—a critical safety feature in high-power applications. The module contains advanced semiconductor technology with optimized switching characteristics for high efficiency and reliability.

Core Features & Customer ValueThe press-pack design with double-sided cooling provides superior thermal performance compared to single-sided cooling modules, enabling higher power density and more compact converter designs. For system designers, this translates to reduced system footprint and improved efficiency. The short-circuit failure mode is particularly valuable in series-stacked applications, as it prevents catastrophic system failure and allows for continued operation with reduced capacity until scheduled maintenance.The high voltage and current ratings make this device suitable for the most demanding power conversion applications. The robust construction ensures reliable operation under extreme electrical and thermal stress, contributing to system availability and reduced lifecycle costs. For utility engineers, this reliability is essential for critical infrastructure like HVDC transmission links where downtime can have significant economic impacts.Typical ApplicationsIn HVDC transmission systems, multiple 216VC624 thyristors are stacked in series to form valves capable of handling several hundred kilovolts. These valves are the core components of converter stations that transmit gigawatts of power over long distances with minimal losses.In industrial applications, the thyristor is used in large variable speed drives for pumps, fans, and compressors in the multi-megawatt range. The robust design handles the demanding operating conditions found in industries such as mining, metals, and oil & gas.
