Flyback converter input capacitor
WebTo calculate the input filter capacitor, we need to calculate the peak voltage of the DC bus at minimum line voltage, then by calculating the discharge time and the rms current of … The schematic of a flyback converter can be seen in Fig. 1. It is equivalent to that of a buck-boost converter, with the inductor split to form a transformer. Therefore, the operating principle of both converters is very similar: • When the switch is closed (top of Fig. 2), the primary of the transformer is directly connected to the input voltage source. The primary current and magn…
