| titleOfInvention | Flyback power conversion circuit and conversion control circuit and control method thereof |
| abstract | A flyback power converter circuit, a conversion control circuit and a control method thereof. The flyback power conversion circuit includes a power transformer, a primary side switch and a conversion control circuit. The conversion control circuit calculates the corresponding upper limit frequency according to the output current by a frequency upper limit function in the dead time of the discontinuous conduction mode, then obtains a frequency upper limit shielding period after the primary side switch starts to be conducted by the reciprocal of the upper limit frequency, selects a specific one of at least one wave trough of a cross-voltage ringing signal of the primary side switch in an upper limit selection period after the frequency upper limit shielding period is ended, and uses the specific one as an upper limit locking wave trough, and conducts the primary side switch again at the occurrence time point of the upper limit locking wave trough. |
