Phase module high voltage variable frequency frame 3BHB018008R0003

3BHB018008R0003 Phase Module High Voltage Variable Frequency Module

Phase module high voltage variable frequency controller 3BHB018008R0003

The 3BHB018008R0003 IGCT controller module is a gate controlled turn off switching device that combines the advantages of GTO (gate turn off thyristor) and IGBT (insulated gate bipolar transistor). Its turn off characteristics are like transistors, while its turn on characteristics are like thyristors, with advantages such as high blocking voltage, large power capacity, fast switching speed, low on state loss, no need to turn off absorption circuits, and easy series parallel connection.

　　main features

Multifunctionality and Efficiency: IGCT is renowned for its versatility, efficiency, and cost-effectiveness. They can achieve low on state voltage, thereby reducing operating costs and improving inverter efficiency, typically exceeding 99.6%.

Low conduction loss: The conduction mode of IGCT is similar to that of thyristors, but its turn off mode is similar to that of transistors, so its conduction loss is the lowest among high-power semiconductors. This feature enables it to operate at higher frequencies than similar technologies before.

Integrated gate unit: The gate unit of IGCT has been integrated, simplifying installation and control. Users only need to connect the device to the power supply and fiber optic cable for on/off control.

High switching frequency: Despite its large size, IGCT can achieve high switching frequencies up to 40 kHz due to its fast conversion time and minimal thermal limitations. This feature is crucial for applications that require quick switching.

Safety and protection functions: IGCT includes an open protection network (usually an inductor) to safely manage the current rise rate. Disabling protection is optional, allowing customization while maintaining security standards.
