可逆运行 meaning in English

push-pull running

In addition , by using igbt in main loop of the system , control and operation of power elements is easy and reliable , and reversible flow of field current can be realized
而采用igbt构成系统的主回路，功率器件控制容易，工作可靠，可以实现励磁电流的可逆运行。
Meanwhile , fully - controlled igbt enables reversible flow of field current and reduce in the size of filter elements of main loop , so that the complete of device becomes smaller and lighter
而全控式的igbt不仅可实现励磁电流的可逆运行，而且由于提高斩波频率，使主回路滤波器件的体积大大减少，从而使整个装置体积减小、重量减轻。
