In a two-switch flyback topology, a high-side power MOSFET – placed between the input voltage rail and the transformer – and snubber diode are added to help overcome the limitations of conventional flyback topology as the overall voltage stress is equally split between the two transistors. This is particularly valuable in high-voltage applications such as auxiliary power supplies supplied by a three-phase input rail. A dual-switch flyback topology also removes clamping losses by recycling the leakage energy to the input side via the two diodes, thus boosting efficiency and reducing thermal stress while clamping the maximum voltage stress of the power MOSFET to the input voltage. We offer a range of controllers supporting quasi-resonant mode, power MOSFETs, diodes and protection devices as well as a range of hardware and software development and evaluation tools to help design high-efficiency two transistor flyback AC-DC converters. 阅读更多

Advantages of a two-switch configuration

This is particularly valuable in high-voltage applications such as auxiliary power supplies supplied by a three-phase input rail. A dual-switch flyback topology also removes clamping losses by recycling the leakage energy to the input side via the two diodes, thus boosting efficiency and reducing thermal stress while clamping the maximum voltage stress of the power MOSFET to the input voltage.
