  4. Secondly the detection precision is only related to the synchronization phase but not to the amplitude of the mainline voltage because that it uses the optimized pulses synchronous with the mainline voltage as modulation signals. thirdly it decreases the requirement of the input low pass filter and eliminates the error resulting from the direct component and even harmonics of load current. the most significant merit is that it can eliminate the effect of a few low order odd harmonics and the detecting circuit is easy to be implemented

    模擬和實驗結果表明該方法的主要優點有：不需使用乘法器進行信號調制，調制信號採用與電網電壓同步的優化特定脈沖，其檢測精度只與同步相位有關，而與電網電壓幅值無關；降低了對輸入低通濾波器的通頻帶要求，直流和偶次諧波分量對檢測精度沒有影響；突出的優點是可以消除有限個低奇次諧波對檢測結果的影響。
