CONTACTLESS TYPE POWER CONVERSION SYSTEM

摘要

PURPOSE: A contactless type power conversion system is provided to reduce the total size and the weight and enhance the durability by forming the second transformer as a coreless transformer. CONSTITUTION: A contactless type power conversion system includes a first conversion unit(A) and a second conversion unit(B). The first conversion unit includes an inverter and a first transformer. The inverter(2) is used for converting the DC voltage and the AC voltage to the AC voltage having a predetermined frequency. The first transformer(3) is connected to the inverter in order to change the flux, periodically. The second conversion unit includes a second transformer and a rectifier. The second transformer(5) is connected to the first transformer by using a contactless method. The second transformer shares the flux of the first transformer. The rectifier(7) is connected to both ends of the second transformer.
