摘要
本文提出一种采用由联电感式逆变器实现ＰＷＭ波形输出的新方法，即克服了以往晶闸管逆变器输出简单方波电压、谐波成分高的缺点，又没有晶体管逆变器易出现二次击穿、短路保护难的问题，经实验证明效果良好。
new method of PWM control by using series inductance inverter is proposed.Not only theexistence of large harmonic component resulted from the use of SCR inverter is eliminated,but also theproblems of secondary breakdown and difficulties in short circuit protection are avoided.The proposal isverified in experiment with expected results.
