【Abstract】 This paper introduces how to calculate the impedance of a serial multi-output-coil voltage transformer with power conversion method. The existence of current differences of secondary coils were considered when the current distribution of the separate secondary coils were determined. A formula is given to calculate the impedance of serial voltage transformers with two or three output coils, which may be applied to product design.更多还原
