2. Operating Principle

This module adopts advanced power electronics technology and may include components such as Integrated Gate-Commutated Thyristors (IGCTs). It adjusts the phase angle of alternating current (AC) by controlling the conduction angle of thyristors, thereby realizing AC phase control. It converts the AC voltage on the secondary side into direct current (DC) voltage, which is used to supply power to the capacitors in the DC circuit.

In motor operation mode, the module functions like an inverter unit in braking mode.

In braking mode, it operates like an inverter unit in motor operation mode.

3. Application Scenarios

Industrial Automation: Suitable for various industrial scenarios, such as motor control in manufacturing. It enables precise adjustment of motor speed and torque, improving production efficiency and product quality.

Power Systems: Used in high-voltage frequency converters and other power equipment to provide efficient rectification solutions and reduce energy consumption. Meanwhile, it can monitor and control voltage and current in power systems to ensure stable operation of the power grid.
