The Estimation Method of the Efficiency of Isolation Transformer

The design of a isolation transformer based on equivalent circuit model haven been given in several papers. once the circuit parameters are obtained, they are used to compared with the simulation results. However, this method has some drawbacks. Hence, in this paper, we propose a low-cost method to estimate the efficiency of the isolation transformer, considering it is the key factor of the transformer, based on the equivalent circuit parameters which can be obtained from simulation results or equivalent circuit model. Once the estimated efficiency is low, the parameters can be optimized. Hence, it can be used to reduce the design period. It should note that although the method proposed in this paper is for isolation transformer design, it can also be applied in the general transformer design.
