One approach is the soft switch technique that is used to reduce switch loss.

首先，利用准谐振软开关技术能够有效降低开关损耗，提高效率。

Test results proved that the motor had lower current harmonic, more efficient use of DC supply voltage than SPWM, less switch loss of power switch.

实验结果证明，系统电动机电流的谐波失真较小，直流母线电压利用率比常规的正弦波脉宽调制（SPWM）有了较大的提高，功率器件的开关损耗较小。

Double space vector modulation can realize zero current commutation of the rectifier side, greatly reduce the switch loss, and improve the efficiency of the converter.

双空间矢量调制两级协调控制能实现整流级零电流换流，极大地减少了开关损耗，提高了变换器的效率。

Martinez denied that the switch was because of his primary loss and said he was "disappointed" but not "bitter" toward his former Democratic colleagues for failing to support repeals of the so-called marriage penalty and estate taxes.

Update: The Novatel PR Team has contacted me and informed me that you can go into settings and set 3G or 4G only mode (this pdf user manual has the details.) I suppose for people using just 4G this could mean loss of connectivity entirely rather than the annoying switch back and forth.

So moving Hook to full-back would be a huge loss to Wales' midfield if it is decided a positional switch is required.
