摘要
依据等离子体荷电喷雾的特点,以IGBT为核心器件,设计了脉宽调制型(PWM)15kHz高压逆变电源,介绍了逆变电源主回路、PWM控制电路及过流保护回路。试验结果表明:在喷雾中使用等离子体技术,不仅喷雾的特性达到了改善,而且还增加了雾滴的荷电数量。
According to the characters of plasma charge spraying, a kind of IGBT inverter power supply used in charge carrying device for spraying is introduced in this paper. It presents a 15kHz high-voltage DC pulse power of width modulation （PWM） and introduces the principles of the main circuit,the PWM control circuit and the protective cireult.The experimental result shows that not only the performance of spraying is improved but also its amount of charge is increased.
