Function of capacitance(3)

The energy storage capacitor collects the charge through the rectifier and transmits the stored energy through the converter lead to the output of the power supply. Aluminium electrolytic capacitors rated 40V 450VDC with a capacitance between 220U 150000uF (e.g., EPCOS B43504 or B43505). Is more commonly used. According to different power supply requirements, the device sometimes adopts the form of series, parallel or its combination. For power supply with power level exceeding 10KW, the large volume spiral terminal capacitor is usually used.
