General LED driver switching power supply main circuit from the input electromagnetic interference filter (EMI), rectifier filter circuit, power conversion circuits, PWM control circuit, the output rectifier filter circuit so on. Filter circuit in the input filter inductance required filtered AC input voltage of the high-frequency clutter components, while preventing the power grid in the high-frequency interference; in power conversion circuit need to use a transformer to play stored energy, transfer energy and release energy the role of the DC voltage is transformed into an unstable high-frequency pulse voltage; output rectification filter circuit also need to use the output transformer and filter filtering, anti-interference.
