WebSingle switch versus double switch flyback In the single switch flyback, an overvoltage spike is applied across the power switch at each turn off. The peak value of this overvoltage depends upon the switching time, the circuit capacitance and the primary to secondary transformer leakage inductance. WebNov 5, 2016 · The single stage PFC flyback converter remains the topology of choice in many off line AC-DC LED power supplies. This is largely due to its low component count and cost, combined with efficiency of around 90%, high power factor and low line current harmonics (iTHD) over a wide AC input voltage range. Only a single MOSFET switch is … WebThe VPT series primarily uses flyback and forward topologies. They are simple, proven, and reliable. And they can accommodate a wide input voltage range as shown in Table 1. Continuous operation is from 15 or 16V up to 40 or 50V, and transient capability is up to 50 or 80V.
