The most popular phase lock controller is baed on the zero-crossing detection,which has a very low bandwidth as well as the slow response. This paper introduces a new method which can get over the disadvantage of the traditional one. The new method just uses the trigonometric function orthogonal conversion to get the real-time phase error,which can not only improve the dynamic response of the phase lock loop,but also provide a convinient way to detect the islanding condition. The method had been implemented in the real product by using the TI C2000 Piccolo B MCU.
