The property of the welding inverter system takes a great role on the container manufacturing production efficiency and welding quality. In this paper, a novel digital controlled welding inverter system based on Digital Signal Processor (DSP) was proposed, and the hardware architecture and software control flow chart were designed. The full bridge soft switching topology was adopted and a special drive circuit was designed to improve the energy transfer efficiency and reliability of the welding inverter. A new current waveform control method with medium current waveform was proposed to control and adjust the growth and transition of each droplet, therefore to improve the welding quality when the welding speed increased. The experimental results indicate that the developed welding inverter system can reach perfect welding quality in the condition of high speed welding process.
