Device Advantages
Combining the large capacity of GTO with the fast switching characteristics of IGBT, the switching speed is much faster than traditional GTO
Low On-State Voltage Drop, lower overall power loss in high-power operation conditions
Gate Commutation Structure, no complex buffer circuit required for turn-off, simplifying the converter topology
Integrated Complete Drive Protection, single module can directly be used as a power arm unit of the converter

Typical Application Scenarios
Medium and high voltage high-power frequency converters
Main drive of rolling mills, mine hoists, high-pressure frequency conversion of fans and pumps (6kV/10kV level)
Flexible DC transmission VSC-HVDC
Grid connection commutation valves for offshore wind power, urban flexible DC distribution networks
Power grid energy management FACTS
SVC static reactive power compensator, STATCOM static synchronous compensator
High-power power conversion for new energy
Large-scale onshore/offshore wind turbine converters, photovoltaic centralized inverter stations

Spare Parts and Replacement Instructions
The complete assembly part number 3BHB018162R0001 for maintenance procurement is the standard spare part, including IGCT chip + driver board + water-cooled base assembly; only 5SHY4045L0001 is a separate chip and cannot be directly used in the machine.
For similar models in the same series, refer to:
5SHY35L4520: 4500V/4000A small power version
5SHY55L4500: 4500V/5000A larger current IGCT
Maintenance points for the equipment:
The water-cooling circuit must use deionized pure water to prevent scaling and chip breakdown
The polarity of the 24V control power supply on the driver board must not be reversed, as it is prone to burning out the gate circuit
During installation, the water-cooling contact surface must be evenly coated with thermal conductive silicone grease to avoid local overheating and damage to the IGCT
