摘要
采用模拟控制方法对串联半桥式可控硅逆变焊机输出特性的控制,其中包括陡降特性控制、平特性控制、空载电压控制、电弧力控制、截流特性控制、脉冲电流控制等,以及采用这些控制方法所获得的外特性曲线。
Through the use of analog control method,study output characteristic control of serial semi-bridge SCR inverter arc welding machine and external characteristic obtained by these control methods. The control methods include steep dropping constant-voltage,no-load voltage,arc force,cut-off current and pulsed current etc.
