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.
Our products and solutions
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.
