Flyback current control
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. WebA flyback converter in peak current mode control (PCMC) is most commonly used in switching mode power supply (SMPS) circuits for low output power applications where …
