www.power-supplies.com.auswitching power supply, as shown in figure 1.3, rectifies and filters the voltage directly from AC mains (off-line) without using a low-frequency transformer. The capacitance of the bulk capacitor can be quite small due to the high rectified voltage. Switching power supply uses a high-frequency transistor to chop the high DC

www.st.comBulk capacitor will be chosen with maximum operating voltage 25% greater than the maximum supply voltage, considering also power supply tolerances. For example, with a 48 V nominal power supply, with 5% tolerance, maximum voltage is 50.4 V, then operating voltage for the capacitor should be at least 63 V. 2.4 Layout Considerations
