A high-frequency switching power supply for industrial electrolytic fluorine production and its control method

Abstract

The invention discloses a high-frequency switching power supply for industrial electrolytic fluorine production and a control method thereof, wherein the power supply includes a monitoring system and multiple DC high-frequency switching power supply modules, and the output sides of the multiple DC high-frequency switching power supply modules adopt a parallel connection mode connection; the monitoring system is used to control multiple DC high-frequency switching power supply modules to output pulse voltage synchronously or to output pulse voltage uniformly in turn. The present invention controls multiple DC high-frequency switching power supply modules in a synchronous output pulse voltage working mode or a uniform rotation output pulse voltage working mode in an orderly manner through the monitoring system, avoiding voltage cycle disorder, making the output voltage more controllable, and improving efficiency. It can be widely used in industrial high-power DC high-frequency switching power supply.

Description

technical field [0001] The invention relates to an industrial high-power DC high-frequency switching power supply, in particular to an industrial electrolytic fluorine-producing high-frequency switching power supply and a control method thereof. Background technique [0002] At present, the high-frequency switching power supply has been used instead of the thyristor rectifier in the industrial production of fluorine gas. Each electrolytic tank corresponds to its own high-frequency switching power supply. This not only makes the power supply of each tank independent, flexible and convenient in operation and maintenance, but also saves electric energy. efficient. Each fluorine-making electrolytic cell requires a large current, and the high-frequency switching power supply needs to be composed of multiple DC high-frequency switching power supply modules to provide the required current for the electrolytic cell. The existing high-frequency switching power supply only uses multi...

AI Technical Summary

Problems solved by technology

The existing high-frequency switching power supply only uses multiple DC high-frequency switching power supply modules to share the current required by the electrolyzer. The waveform output by the power supply is a disorderly combination of outputs from multiple power supply modules. The output waveform of the power module is controlled to affect the efficiency of fluorine production
