The flyback converter is an isolated power converter. The two prevailing control schemes are voltage mode control and current mode control. In the majority of cases current mode control needs to be dominant for stability during operation. Both modes require a signal related to the output voltage. There are three common ways to generate this voltage: 1. Use an optocoupler on the secondary circuitry to send a signal to the controller. Webcurrent, I D. Figure 1 – Power waveforms of a typical resonant converter. A quasi-resonant converter is sort of like a resonant converter, but not quite. The power waveforms in a quasi converter aren’t sinusoidal like in a true resonant converter; a QR flyback still retains the distinct, familiar flyback waveform shapes. pho anh hot pot and crawfish
