Research on Zero Dead Time Control with Current Detection

基于电流检测的零死区控制策略的研究

In order to greatly enhance the zero-sequence current active component during the single-phase ground fault, the short-time switch and the resistance paralleled with the petersen coil were controlled when there is a permanent single-phase ground fault in the system.

该方法当系统发生永久性单相接地故障时通过控制开关短时投切与消弧线圈并联的电阻，从而大大增强单相接地故障时的零序电流有功分量。

AC control is a normal application for triacs and SCRs because the turnoff time is decreased when the device is switched off during a zero-crossing.

由于器件在过零时被关断会降低关断时间，所以双向晶闸管和SCR通常用于交流控制。

With personal saving rates still close to zero and debt loads remaining at all-time highs, US consumption is heading for a Japanese-style multi-year adjustment.

鉴于个人储蓄率仍接近于零，而债务负担维持在历史高点，美国消费正趋向日本式的多年调整。
