Flyback converter input capacitor
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… WebJun 3, 2024 · Filtering: It is well known that if not properly designed, flyback converters couple a lot of noise to the input and vice-versa. By splitting the input capacitor into two for example, you could build a PI filter with an …
