Problems solved by technology

Due to the uncertainty of the load connection on the bus and the instability of the power demand of the load itself, sometimes the output power of the high-frequency inverter power supply cannot fully meet the power demanded by the load. Properly adjust the power to meet the diverse load power needs

Abstract

The invention provides a high-frequency inverter power supply power regulation method and regulation system. The method comprises steps of judging whether a ratio of real-time output power corresponding to a high-frequency inverter power supply to real-time required power corresponding to a load is greater than a first preset ratio or not, if yes, reducing the real-time output power correspondingto the high-frequency inverter power supply to a preset value, and connecting a bus with an electric energy storage device to charge an electric energy storage device, if not, judging whether the ratio of the real-time output power corresponding to the high-frequency inverter power supply to the real-time required power corresponding to the load is greater than a second preset ratio or not, if yes, reducing the real-time output power corresponding to the high-frequency inverter power supply to a preset value, and if not, increasing the real-time output power corresponding to the high-frequencyinverter power supply to a preset value, the bus being connected with an electric energy storage device, and the electric energy storage device discharges to the bus. The method is advantaged in thatthe power of the power supply is adjusted in real time according to the required power of the load.

Description

technical field [0001] The invention belongs to the technical field of high-frequency inverter power supplies, and in particular relates to a method and system for adjusting the power of high-frequency inverter power supplies. Background technique [0002] High-frequency inverter power supply has dual functions of power supply and inverter. On the one hand, it can supply power to the load. On the other hand, it can properly adjust its own output power according to the needs of users, so as to adapt to different power requirements of the load. . [0003] There is no certain criterion for load connection on the bus, and it is often connected and disconnected at any time according to the needs of users. Due to the uncertainty of the load connection on the bus and the instability of the power demand of the load itself, sometimes the output power of the high-frequency inverter power supply cannot fully meet the power demanded by the load. The power is properly adjusted to meet ...
