AI Technical Summary

Technical Problem

Power regulators are prone to generating harmonics and electromagnetic interference at the moment of process switching or the moment of main heating circuit power switch, which can cause abnormal fluctuations in load circuit current and even burn out the main circuit, affecting network communication and group control functions.

Method used

Design a dual-bus redundant power regulator, which combines a built-in auxiliary heating PECVD reaction chamber, adopts a microprocessor and a communication redundancy module, and achieves redundancy through RS485 and TCP/IP communication ports. It uses a thyristor drive circuit to suppress interference, detects and counts load circuit current distortion, uses a status counter alarm, and combines a power distribution algorithm and interference suppression circuit to prevent thyristor false triggering.

Benefits of technology

It improves the stability of the load circuit current, reduces the number of downtimes due to faults, avoids burnout of the main circuit, and ensures the reliability and precise temperature control of the power regulator.

Abstract

This invention discloses a power regulator and its load circuit current abnormal fluctuation handling method in the field of circuit power regulation technology. It includes a built-in auxiliary heating PECVD reaction chamber and a dual-bus redundant power regulator. The built-in auxiliary heating PECVD reaction chamber includes a sealed water-cooled flange, an internal thermocouple, a support component, a graphite boat, an external thermocouple, a quartz tube, a resistance heating wire, an insulation layer, a support flange, an air inlet flange, and an auxiliary heating device. It implements RS485-based Modbus communication protocol and TCP / IP-based Modbus communication protocol through two communication ports, achieving redundancy of communication ports, as shown in Figure 3. Simultaneously, a shared memory mechanism is adopted to compare the communication data based on RS485 and TCP / IP, and then map it to shared memory, ensuring the reliability of the communication data.
