Key Features and Advantages

Dual-Core Architecture: Balances Precision & Speed

• PowerPC handles complex algorithms to ensure steady-state accuracy of voltage/current control.
• FPGA enables ultra-high-speed signal processing, shortening instantaneous current response to 1/3 of the switching cycle, allowing fast load tracking and oscillation-free power stepping.

Multi-Mode Control & Flexible Adaptation

• Built-in Instantaneous Current Control (ICC) and improved I2CC algorithm to compensate for transformer winding resistance.
• Supports 2-step / 3-step load angle switching to avoid current oscillation.
• Integrated balance control corrects current imbalance caused by asymmetric transformer impedance via independent phase compensation angles, improving DC-side power quality.

High Reliability & Safety Design

• Multiple protection mechanisms: emergency stop (NOTAUS_PORT), input over-limit detection (EINGNGSFEHLER_PORT), etc., for fast gate drive cutoff.
• Supports Zero-Voltage (ZV) / Zero-Current (ZC) switching detection to prevent hard-switching damage and ensure safe operation of soft-switching topologies.

Industrial Compatibility & Scalability

• Galvanically isolated drive for IGCT, IGBT via optical modules, compatible with ABB 5SHY series IGCT and Infineon dedicated diodes.
• Supports cooperation with Auxiliary Resonant Commutated Pole (ARCP), medium-high frequency transformers, and scalable to multi-module series/parallel systems.

Low Loss & High-Efficiency Control

• Dynamic voltage balancing with lossless snubbers reduces switching losses of series power devices.
• Precise load angle control and harmonic suppression algorithms lower losses in transformers and filters, helping system efficiency exceed 99%.

Installation & Maintenance

Installation Requirements

• Mount in a shielded industrial control cabinet to avoid electromagnetic interference.
• Low-inductance wiring layout between the controller and power devices (e.g., IGCT stack); optical cables routed separately from power cables.
• Powered by an independent 24 V galvanically isolated auxiliary supply with UPS backup for safe shutdown during power failure.

Commissioning & Configuration

• Control algorithm development and code generation via MATLAB/Simulink & Real-Time Workshop, supporting fast download to PowerPC.
• FPGA integrates customizable blocks; custom logic (e.g., special topology algorithms) can be extended via VHDL.
• TRGR_PORT trigger port for oscilloscope connection to synchronously observe switching signals and current waveforms.

Maintenance Highlights

• Regularly check optical module connections and clean interface dust.
• Monitor operating data (PowerPC/FPGA temperature, power status, fault logs) via MODBUS.
• Full calibration every 2 years, focusing on current/voltage sampling accuracy and trigger signal synchronization.

Troubleshooting

• EINGNGSFEHLER_PORT triggered: Check if load angle or compensation angle inputs exceed rated range.
• Phase current imbalance: Adjust PHIiP_PORT or enable balance control algorithm.
• Emergency stop (NOTAUS): Identify trigger source first; restart via EINSCHALTER_PORT only after fault clearance.
