Abstract:To solve the problems of measuring and calculating the efficiency of the high-power rectifier system, a multi-point measurement and efficiency-analysis method based on the optic fiber ethernet communication is presented. On the basis of the efficiency analytic system of the high-power rectifier system which based on the inductive filter technique, the paper describes the whole design scheme of the efficiency analytic system, measuring principles and the algorithm of the system. Providing a kind of data compression and reconstruction algorithm based on the Fourier transform and a method of indirect inversion of heavy direct current. Then proving the method is correct and can be well applied in practical project through simulation and experiments. The project case indicates that the efficiency analytic method can correctly calculate the efficiency of the power-supply system which used by industry rectifier system, achieve the goal of getting the loss and efficiency of the rectifier transformer and the rectifier, and then provide a proof of improving the efficiency of the equipments and saving energy of the system.
