WebFlyback converters are often used in switch-mode power supplies for AC/DC and DC/DC conversion, especially for the low-to-mid power range (about 2W to 100W). In this power range, flyback converters offer a very competitive size, cost, and efficiency ratio. ... When working at high duty cycles (>50%), subharmonic oscillation appears and slope ... WebCurrent mode switching regulators which operate with a duty cycle greater than 50% and have continuous inductor current can exhibit a duty cycle instability known as subharmonic oscillations. This effect is not harmful to the regulator and in many cases it does not even affect the output regulation.
