Using equivalent circuit, a calculating method of ripple current of single rectifier combined with transformer was studied. The validity of the equivalent circuit method developed in this study was examined by comparing its results with those obtained from Irie's method. In order to develop the model, some circuit conditions were considered, and the results obtained are as follows.
1) Employing this method, ripple current could be easily calculated according to the object and required accuracy.
2) In emf load, the error is almost not affected by X? while greater E??/E? makes greater error.
3) In resistance load, error decreases with the increasing R? while increases with increment of X? of ±10% is becoming narrower with the increase ofX?value.
