Abstract

The invention relates to a welding machine control circuit. The welding machine control circuit comprises a voltage input module, a rectifier module, an energy storage module, an inversion module, a PWM energy storage control module and a PWM driving control module. The PWM energy storage control module controls the energy storage module to store energy according to output of the energy storage module. The PWM driving control module transmits input voltage of a welding machine to the PWM energy storage control module and stabilizes output power of the inversion module according to input voltage of the welding machine, current of the energy storage module and an output current source and output voltage of the welding machine. According to the welding machine control circuit, the PWM energystorage control module controls the energy storage module to supply enough energy to the inversion module; the PWM driving control module synthesizes the input voltage of the welding machine, the current of the energy storage module and the output current and the output voltage of the welding machine to control the output power of the inversion module. Accordingly, the stability of the output power of the welding machine is guaranteed under the condition of changing the input voltage of the welding machine. The welding machine control circuit has good wide voltage adaptive ability.

Description

technical field [0001] The invention relates to the technical field of electric welding machines, in particular to a welding machine control circuit. Background technique [0002] With the increasingly wide range of applications of inverter power welding machines, and the current differences in power grids around the world, the distinction between civil, light industry, and industrial applications has become increasingly blurred. Various voltage inputs (single-phase 110V, 220V, 380V, three-phase Phases 220V, 380V, 440V, generators, etc.) are becoming more and more complex, so higher requirements are put forward for the adaptability of the input voltage of the inverter welding machine. [0003] At present, there are mainly the following ways to adapt to the welding machine design in different complex voltage environments: design 1, through the series and parallel transformation of two inverter full bridges to broaden the applicable working voltage range; design 2, using manua...
