A TRANSFORMER USING FREQUENCY CONVERSION DEVICE, ESPECIALLY PWM MODULE AND THE METHOD THEREOF

摘要

A transformer using a frequency conversion device, particularly PWM(Pulse Width Modulation) module and a method for manufacturing the same are provided to improve spatial efficiency and facilitate transfer by coupling the frequency conversion device with a high frequency transformer. A transformer includes an input side frequency conversion device(10), a high frequency transformer(20), and an output side frequency conversion device(30). The input side frequency conversion device converts a frequency of an inputted AC voltage into a high frequency. The high frequency transformer is connected to the input side frequency conversion device and steps up or down an AC voltage with the converted frequency. The output side frequency conversion device is connected to an output side of the high frequency transformer and converts a frequency of the stepped up or down AC voltage into a low frequency.
