Filter Technology in the Switching Power Supply

Abstract:

With the increase of switching frequency of power switch, EMI noise pollution becomes more and more serious. In order to solve this problem, in this paper, the switch power supply filter and passive EMI filter, active EMI filter is studied. It mainly research active EMI filter with feed forward , non-inductive current detection device of active EMI filter and active EMI filter for three-phase inverter motor. To solve this problem which is that EMI noise pollution has become more serious along with the increase of switching frequency switch power supply, the increasingly serious pollution make the EMI filter technology have a wide range of applications and put forward higher request to filter technology
