Hello, I tested the prototype by changing the input voltage under heavy load conditions, with the input ranging from 220V to 900VAC. I found that the operating frequency of the converter remains constant at 16KHz, but the maximum operating frequency I…
Please find attached the schematic and waveforms for the primary current, bridge switch VDS, secondary output voltage, CS output, and output load current.
Update-
-The compensation values were updated as suggested; however, the output voltage rises to…

The Triggering Observation
During teardowns of 23 failed EV chargers and phone adapters (2019-2023), MOSFET failures accounted for 81% of catastrophic faults - yet OEMs bury this component in obscurity. How can a sub-$0.1 part dictate the success of $500M…

In some high-frequency switching circuits, the Miller effect of MOS tubes has the unpleasant disadvantages of extending the switching frequency, increasing power consumption, and reducing system stability. As shown in the figure below, there is a small…
