Abstract

The invention provides an energy storage welding machine control method and a device and relates to the welding machine technology field. The energy storage welding machine control method comprises the following steps of starting an energy storage welding machine and using a boosting transformer to boost a three-phase alternating current; triggering and starting a three-phase full bridge rectification module and rectifying the boosted three-phase alternating current into a direct current; charging an energy storage capacitor group and using the rectified direct current to charge the energy storage capacitor group; and detecting the charging voltage of the energy storage capacitor group in real time, and when the charging voltage reaches a preset voltage value, switching the three-phase full bridge rectification module into a single-phase rectification mode. By using the energy storage welding machine control method, a charging current is stable, charging efficiency is high, and the stability of the welding machine can be effectively increased. By using the energy storage welding machine control device, the charging current is stable, the charging efficiency is high and cost is low.

Description

technical field

[0001] The present invention relates to the technical field of welding machines, in particular to a method and device for controlling an energy storage welding machine. Background technique

[0002] In the prior art, it is composed of PLC, three-phase intelligent charging module, voltage detection board, and current detection board. The welding voltage value is set through the touch screen, and then the PLC calculates the analog voltage value required by the three-phase intelligent module, and outputs the voltage The three-phase intelligent charging module controls the switching on and off of the thyristor to charge the capacitor. When the PLC sends the charging signal to the three-phase module, it continuously detects the real-time voltage on the capacitor, feeds back the voltage result once every 10ms, and controls the analog voltage value according to the feedback voltage value to adjust the charging current and speed.

[0003] This method uses PLC as the...
