| Abstract: | A reference sinusoidal circuit based on digital technique and synchronous with the power system voltage is analyzed. The design criterion of the key circuit parameters is given. Experimental results agree with the theoretical analysis.The reference circuit has the advantages such as synchrony with the power system voltage, low THD, adjustable peak voltage which is free from the fluctuation of the power system voltage, simplicity and utility, low cost.The reference circuit has important applicative value in AC/AC conversion system with high frequency ac link and UPS. |
