product description:
High-frequency transformers and reactors for new energy vehicle charging piles are mainly used in vehicle charging piles and new energy vehicle inverters. In order to achieve electrical isolation and reduce the volume and weight of transformers, the structure of electric vehicle charging piles uses high-frequency transformers for isolation.With the increasing capacity of electric vehicle charging piles, the loss of high-frequency transformers is also increasing.In order to reduce the leakage inductance and iron loss of the high-frequency transformer under the condition of large output current, the design of the high-frequency transformer becomes more and more difficult.High-performance electric vehicle fast charging piles came into being.High-performance electric vehicle fast charging piles can not only realize all the functions of traditional electric vehicle charging piles, but also have the advantages of fast charging speed, diverse charging objects, and easy design of high-frequency devices.Electric vehicle charging piles usually use a single-phase or three-phase uncontrollable rectifier bridge to rectify single-phase alternating current or three-phase alternating current into direct current, and then convert it into a power supply with controllable direct current voltage and direct current through a DC-DC conversion circuit.Battery charging.
