Tool/software:
I designed a flyback converter using the UC2845.
The output meets the design specifications; however, when operating in Peak Current Mode, the duty cycle becomes highly inconsistent under all load conditions. Specifically, the waveform exhibits irregularities with alternating maximum (50%) and minimum duty cycles.
In contrast, when I operate the system in Voltage Mode according to the manufacturer's recommendations, this issue does not occur.
Can anyone help me understand what might be causing this?
