4. Working Principle
These two modules operate in coordination to complete electric energy conversion and precise excitation control, consisting of two core procedures: energy conversion and closed-loop regulation.
As the front-end core component of the excitation system, 3BHL000382P0101 samples 3-phase AC power from the grid, executes preliminary AC-DC rectification and voltage regulation via internal circuits, and outputs basic excitation electric energy according to preset system parameters.
As the back-end core power device, 5SHX0445D0001 IGCT performs high-speed switching to accurately regulate output frequency, voltage and current, correct waveform distortion and improve power quality.
During operation, the built-in closed-loop control system collects real-time data including terminal voltage, current and load status of the motor, compares measured values with standard operating parameters, and adjusts switching status and output power within milliseconds to offset deviations caused by grid fluctuation and load change.
