In a drive system of power transistor inverter-motor, not only can it be used in fine control of motor current waveform, phase, amplitude and frequency, but can also be used to sense, fault current.
The air stripline feeding network is featured with low loss, high power capacitance, and it is easy to control its amplitude and phase.
空气板线馈电网络具有损耗小、耐功率高、幅相控制容易等特点而广泛应用于平面阵列天线中。

In this paper, we propose and discuss two new control methods for three phase shunt APFs: the sinusoidal line current control method and the instantaneous reactive power compensation control method.
