working principle
Stage description
Signal acquisition receives current and voltage feedback signals from CT/PT+encoder speed feedback
Given the speed/torque given signal (4~20mA/Modbus) received from the upper system (DCS/PLC)
Control algorithm DSP executes vector control (FOC) algorithm to calculate the required voltage vector
PWM modulation FPGA generates multi-level PWM trigger pulses to drive power unit IGBT
Power coordination coordinates the output of multiple power units to achieve multi pulse rectification and reduce harmonics
Safety interlock overcurrent/overvoltage/undervoltage/short circuit protection, automatically blocks triggering pulse in case of fault
Communication management communicates in real-time with the upper system through Modbus/Profibus/Ethernet
