Figure 1 This simplified flyback converter can operate in either DCM or CCM. When Q1 turns off during period 1-D, T1’s secondary voltage polarity reverses, which allows D1 to conduct current to the load and recharge COUT. Current in D1 decreases linearly from its peak to zero during time t2. Once T1’s stored energy is depleted, only.
In the following we will learn the step by step instructions regarding how to design a DCM mode flyback converter. DCM Flyback Design Equations and Sequential Decision Requirements Step#1: Assess and estimate your design requirements. All SMPS design must begin by assessing and determining the system specifications.

Air gap must be calculated for the flyback transformer, since it is operating single-ended and uses only half the flux capacity. ... Since V in,min = 85VAC, then V in,min = 85*1.4-20V for ripple and diode drop gives about.

You can see the schematic of the flyback circuit below. As I stated, this product is been using in the field for years but I didn't receive any product with a problem regarding this diode. This is the first time and all of these 10pcs products is used on the boat. So I think maybe there would be something in the boats causing this issue.
