Product performance

The driver board is precisely matched with the original factory calibration of the IGCT. The gate charge and switching timing are accurately adapted. It is not allowed to ｒｅｐｌａｃｅ the driver board or power components with other models at will.

The complete set is equipped with multiple protections such as gate undervoltage, device short circuit direct connection, IGCT overheating, and driver overload. The fault optical fiber signal is transmitted back to the main control system, and the pulse is quickly blocked to prevent IGCT breakdown damage.

The air-cooled press-fit structure does not require a water cooling pipeline system. The equipment operation and maintenance cost is lower, and it can operate continuously at full load for 7×24 hours.

The thick copper foil PCB design of the driver board is designed for vibration resistance and strong electromagnetic interference resistance. It is suitable for dusty, high-temperature, and high-harmonic industrial harsh cabinet environments.

An internal waveform optimization circuit is built-in, which suppresses the dv/dt voltage spikes during switching, effectively reduces the overall switching loss and electromagnetic radiation of the machine, and improves the efficiency of the inverter.

The modular plug-in terminal structure makes it convenient and quick to disassemble and assemble power units, perform on-site fault repair, and ｒｅｐｌａｃｅ spare parts.
