浅谈高频变压器检验用要求及测试方法

Discussion on inspection requirements and test methods of high frequency transformer

目前高频变压器生产和制造工艺方法都很多,但是不象低频电子变压器可以对空载及负载电流及损耗和输出电压及负载进行测试,高频变压器需要电源整个组合器件,才可测试,因此行业中绝大多数厂家只对开路及短路电感及圈数比及极性,直流电阻及各种耐压进行全数严格管控,同时对其它参数也必须进行管控。现主要分为从三大关键工序来进行工程管控,保证合格品出货。

at present,there are many production and manufacturing processes for high-frequency transformers,but unlike low-frequency electronic transformers,which can be tested with no-load and load loss,output voltage and load,high frequency transformers require the whole combination of power supply components to be tested.Therefore,the vast majority of manufacturers in the industry only carry out all kinds of open circuit and short-circuit inductance,coil ratio and polarity,DC resistance and various withstand voltage Strictly control and control other parameters at the same time.Now it is mainly divided into three key processes to carry out engineering control to ensure the delivery of qualified products.
