Networked controller of high-frequency inverter power supply and control method thereof

Abstract

The invention relates to a networked controller of a high-frequency inverter power supply and a control method thereof. The controller comprises a control board, a main circuit, a functional circuit and a network interface, wherein, the control board is based on a microprogrammed control unit (MCU) in charge of display and communication functions and a digital signal controller (DSC) in charge of inversion and protection control functions of the high-frequency inverter power supply; a serial peripheral interface (SPI) is adopted between the MCU and the DSC for carrying out high-speed synchronous data information transmission; a network interface is an RS-485 interface; the controller realizes remote control by RS-485 bus networking and can form a power supply network with other power supplies; a remote upper computer can carry out relevant operation on a command sent by the controller in real time and avoid local control; and a controller protocol for realizing network control realizes networked control of the high-frequency induction heating inverter power supply by an Modbus remote terminal unit (RTU) communication protocol which is widely applied.

AI Technical Summary

Problems solved by technology

At present, the high-frequency induction heating inverter power supply in the market generally adopts independent distributed control, most of which cannot realize networked remote monitoring, and has disadvantages such as low degree of automation, high labor intensity for workers, poor safety and reliability, and high equipment cost.

With the expansion of the production scale of the enterprise, the independent decentralized control high-frequency induction heating inverter power supply can no longer meet the needs of industrial production
