This paper proposes a novel zero-voltage and zero-current-switching pwm three-level converter, which introduces a block capacitor in series with the primary winding of the transformer to make the primary current to reduce to zero during zero state.

提出一种新颖的零电压零电流开关PWM三电平直流变换器，它是在基本的三电平直流变换器的变压器一次侧串入一个阻断电容，使一次电流在零状态时减小到零。

In this paper, the soft-starter is based on the transformer so that it can work under the middle voltage. In order to avoid the high voltage and reduce the starting current, a pair of anti-parallel SCR is to be connected with the second winding of the transformer and the primary winding is directly connected with the motors stator.

为了解决上述的问题，本论文研究的设备采用降压起动的方式来减小起动电流，采用开关变压器一次侧连接电动机定子，二次侧与晶闸管串联。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
