Flyback with multiple outputs
WebJan 17, 2024 · The use of the flyback transformer offers several benefits. The first is that the primary and secondary sides of the supply are electrically isolated. Isolation reduces the coupling of transients from the primary side, removes ground loops, and offers greater flexibility in the supply’s output polarity. WebJun 21, 2024 · The flyback is a logical choice when choosing a system topology that must generate multiple outputs from a single power supply. Since the voltage across each transformer winding is proportional to the number of turns in that winding, you can set each output voltage simply by providing the correct number of turns.

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.
