WebJun 16, 2024 · Let's make the calculations for two output voltages as shown in OP's question. I R 6 = V R E F R 6 = I R 5 + I R 7 I R 5 = V o 1 − V R E F R 5 I R 7 = V o 2 − V R E F R 7 Assuming Vo1 should be regulated more tightly than Vo2. Let the regulation factor for Vo1 be K V o 1 = 0.7. So, the regulation factor for Vo2 will be K V o 2 = 1 − 0.7 = 0.3. 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…
