FSKR508 application field and working principleFSKR508 is a combination of frequency synchronous rectifying unit with rotary frequency compensator. It is used in the power balance system with large range of capacity.The application field of FSKR508 is mainly used in the large capacity rotating machinery system, where the capacity needs to be balanced and the regulating speed range is large. FSKR508 can effectively reduce the power line loss and improve the power efficiency, upgrade the running quality of load, and enhance the capacity of the power system and the stability of the system, so that it can meet the requirements of large capacity system running stability.The working principle of FSKR508 is to use phase-locked loop (PLL) technology to detect the peak of AC voltage, and then to adjust the angle of thyristor switch conduction. The voltage and current waveforms of the load will be rectified by synchronous rectifying the input voltage, which is mainly to ensure the synchronization and rectification of current and voltage sine waveforms output by motor. At the same time, thyristor is also used to regulate the magnitude of current and voltage, thereby controlling the output power and speed of the motor.When the user sets the target value of the output voltage and current, the FSKR508 will first compare the gap between the set value and the current value of the output voltage and current, and then choose the appropriate adjustment angle according to the comparison result. The correction angle is also combined with the phase locking control system and the phase advance control system. The characteristics of the phase locking system is fast and accurate angle tracking, while the advantage of the phase advance control system is to reduce the rate of power. mode.From the above, we can see that FSKR508 is an advanced frequency synchronous rectifying switch with a wide range of capacity, which can be applied to the large capacity rotating machinery system. Its working principle is to use the phase-locked loop technology to detect the peak of the AC voltage and adjust the angle of the thyristor switch conduction, so as to rectify the current and voltage waveforms output by the motor, and then control the output power and speed of the motor.
