The ratio of … WebSep 18, 2024 · 1 Answer Sorted by: 5 The primary has an inductance of 38 uH and couples to the secondaries with a turns ratio of 2:1 and 2:1.1. The 2:1 coupling means that the secondary inductance is ( 1: 2) 2 x 38 uH = 9.5 uH. The other secondary has a turns ratio slightly less (2:1.1) and therefore has an inductance of 11.5 uH.
Flyback inductance

WebThe terms flyback or kickback originate from the induced voltage reversal that occurs when the supply current is interrupted. The reversed induced voltage (s) tries to create ( induce ) a current flow. The open switch prevents current from flowing through the power supply. WebIn a flyback topology the drain-to-sourcevoltage across the low-sideMOSFET is the input voltage plus the output voltage reflected to the transformer primary. At least a 20% …
