Flyback with multiple outputs
WebApr 8, 2016 · The flyback converter is the most popular topology for low-power isolated power supplies. While easy to realize multiple outputs with low cost, this topology still has poor transformer utilization and high AC resistance losses. WebFlyback Converter Design Process and Calculations Step 1: Design Inputs Design inputs are either defined by the end application or selected by the designer. These parameters include, but are not limited to, the input and output voltages, power, ripple factor, and operation mode.

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. WebJan 11, 2010 · Multiple high-voltage outputs are easy to generate with a flyback, and the flyback is well understood. However, there are challenges with the flyback: the topology includes unclamped power switch voltages that can ring excessively; it usually needs a two-stage output filter; and cross regulation over zero to full load will not be three percent.
