SYSTEM AND METHOD FOR DETECTING A FUNDAMENTAL FREQUENCY OF AN ELECTRIC POWER SYSTEM |
摘要 |
A system and method to detect the fundamental frequency of an electric input signal using a feedback control loop including a phase error detector, a loop controller, and a digitally controlled oscillator. The frequency detector may detect the fundamental frequency of an electric input signal and produce an output signal representing the fundamental frequency of the electric input signal. The frequency detector may further include a filter that may be coupled to the frequency detector output signal in order to remove spurious tones or noise from the output signal. |
