5SHY4045L0001: Product OverviewThe 5SHY4045L0001 is a high-power IGBT (Insulated Gate Bipolar Transistor) module from ABB’s StakPak series, designed for use in demanding power electronic applications such as medium-voltage drives, industrial power supplies, and HVDC (High Voltage Direct Current) transmission systems. This press-pack IGBT is engineered as a robust switching device that can be assembled into stacks to handle very high voltages and currents. Its primary function is to act as a fast-acting electronic switch, turning on and off the flow of high-power electrical energy in converter circuits like VSCs (Voltage Source Converters).Unlike conventional module packages, the StakPak utilizes a press-pack housing that allows for double-sided cooling, which is critical 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.5SHY4045L0001: Technical Specifications

Core Features & Customer ValueThe press-pack design is the module’s most critical feature, enabling double-sided cooling. This construction significantly improves thermal performance compared to single-sided cooling modules, allowing for higher power density and more compact converter designs. For system designers, this translates to smaller cabinet footprints and improved system efficiency due to lower thermal losses. The ability to stack modules in series reliably is essential for achieving the multi-kilovolt blocking voltages required for medium-voltage drives and HVDC transmission.The short-circuit failure mode is a key safety advantage. In high-reliability applications like HVDC transmission, where system availability is paramount, a device failing to a short circuit allows the system to be designed with redundancy. This fail-safe characteristic prevents catastrophic open-circuit failures that could lead to overvoltages and system-wide damage, thereby enhancing the overall reliability and safety of the power conversion system.Typical ApplicationsIn HVDC Light® transmission systems, multiple 5SHY4045L0001 IGBTs are stacked in series within a submodule to build a Modular Multilevel Converter (MMC). Each IGBT acts as a switch to insert or bypass a capacitor, synthesizing a high-quality sinusoidal voltage waveform with minimal harmonics.In large industrial medium-voltage variable frequency drives (VFDs) for pumps, fans, and compressors, these IGBTs form the inverter stage. They switch the DC bus voltage to create a variable frequency and amplitude AC output to control the speed of high-power motors, typically in the multi-megawatt range, leading to significant energy savings.
