WebA transformer based flyback is ideal for both; it provides galvanic isolation—there is no direct current path between the input and output, and with the appropriate turns ratio and external components, extremely high voltages can be obtained. Optocoupler-Based Isolated Flyback Solutions 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…
