Abstract: | A reference sinusoidal circuit which is based on digital technique and synchronous with the signal of n or 1/n times line voltage frequency is firstly proposed and deeply investigated. The design criterion of the key circuit parameters and the test results are given. The test results agree with the theoretical analysis. The reference circuit has the advantages such as synchrony with the signal of n or 1 / n times line voltage frequency , low THD, adjustable peak voltage which is free from the fluctuation of the line voltage, simplicity and utility, low cost. The reference circuit has important applicative value in the AC/AC variable conversion system with high frequency AC link and UPS. |
