August 3, 2006[Design View / Design Solution] Enhance Synchronous-Rectification Control In Flyback Converters
The transition from diodes to synchronous-rectification (SR) MOSFETs in secondary circuits of flyback converters increases with each new generation of MOSFETs, improving performance at little or no cost penalty. SR MOSFETs can be more efficient than diodes, allowing lower operating temperatures and smaller heat sinks, or no heat sinks at all. However, they require a control circuit to manage their switching behavior in order to emulate a diode. The usual synchronous rectifier control method...
August 3, 2006[Design View / Design Solution] Modes Of Conduction
Various power-converter architectures use their transformer in different modes. In continuous conduction mode (CCM), the magnetic field never completely collapses due to the transformer's mode of operation. Instead, the energizing portion of the electromagnetic cycle begins before the de-energizing portion of the cycle completely converts the stored magnetic field back into electrical current. If you imagine the triangular current waveform that results from a square-wave voltage drive on the...
