The significant benefit of this approach is the ability to achieve voltage conversion ratios of 400V to 12V with no transformer and low internal ...

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… WebFlybacks are designed to work best anywhere between 15 to 150 kHz, so some experimentation is required to find the intended operating frequency. TV flybacks are generally designed for upper audio frequencies, which is the cause of the high pitched noise heard from a muted TV. (If you're over 40 you will need to confirm this with your kids.)
