WebJun 25, 2007 · The flyback delivers power to the load during the off time of the transistor and the rectifiers work as peak rectifiers. That means the output voltages follow the peaks of the transformer secondaries during the flyback period. 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…
