1. Basic Principle of IGCT: The ABB S-093H series products contain IGCT components. Essentially, IGCT is a new type of power semiconductor device. It combines the advantages of thyristors (SCR) and transistors. Thyristors have the characteristics of low on-state voltage drop and the ability to withstand high voltage and large current. However, the turn-off of traditional thyristors requires a special commutation circuit. In contrast, IGCT integrates a gate drive circuit, enabling it to control the turn-on and turn-off through the gate signal just like a transistor. When turning on, when an appropriate positive trigger signal is applied to the gate, electrons and holes inside the IGCT are injected into the conductive channel, causing the device to conduct rapidly, capable of carrying a large current and achieving the transmission and control of electrical energy. When turning off, a reverse signal is applied to the gate, quickly extracting the carriers, causing the device to turn off rapidly and cutting off the current loop.

2. Principle of Phase Measurement and Control:

The S-093H series products have a phase measurement function. It monitors the phase information of the input power supply in real-time through built-in sensors or detection circuits. For example, in an alternating current circuit, voltage transformers (PT) and current transformers (CT) are used to collect voltage and current signals. These analog signals are converted into digital signals through the signal processing circuit, and then analyzed and calculated by a digital signal processor (DSP) or a microcontroller unit (MCU) to obtain parameters such as the phase angle of the power supply. Based on the measured phase information, phase control is carried out. In some applications, such as the motor speed control system, according to the load demand and the set control strategy, by controlling the turn-on and turn-off moments of the IGCT, the phase of the output voltage or current is adjusted, thereby achieving precise control of parameters such as the motor speed and torque. In the power system, the power factor can also be adjusted by controlling the phase to optimize the power quality and reduce reactive power loss.

3. Principle of Redundant Central Processing Unit: Products of this series adopt the design of a redundant central processing unit. The purpose of redundancy is to improve the reliability and stability of the system. When the main central processing unit (CPU) fails, the standby CPU can quickly take over the control tasks of the system to ensure the normal operation of the system. The two CPUs run the same control program simultaneously and continuously conduct data comparison and status monitoring. Under normal circumstances, the main CPU is responsible for the control output of the system, and the standby CPU is in a hot standby state, tracking the operation status of the main CPU in real-time. Once the main CPU shows abnormalities, such as hardware failures or software errors, the standby CPU can detect it and switch to the working state within an extremely short time (usually in milliseconds or even shorter) and continue to execute the control tasks, avoiding losses caused by system downtime.

4. Principle of Collaborative Work: In practical applications, the S-093H series products usually work in collaboration with other modules. For example, they cooperate with signal acquisition modules, drive modules, protection modules, etc. The signal acquisition module converts various external physical quantities (such as voltage, current, temperature, etc.) into electrical signals and transmits them to the S-093H module. The S-093H module processes and analyzes the collected signals, calculates appropriate control signals through phase measurement and control algorithms, and then amplifies these control signals through the drive module to drive power devices such as IGCT to act. At the same time, the protection module monitors the operation status of the system in real-time. When abnormal situations such as overcurrent, overvoltage, and overheating are detected, it promptly sends a signal to the S-093H module. The S-093H module takes corresponding measures according to the preset protection strategy, such as turning off the IGCT, sending out an alarm signal, etc., to protect the safety of the system and equipment.
