Designers often use chargers with flyback topologies to quickly charge energy-storage capacitors (references 1 and 2). In a flyback topology, the energy transfer takes place only when the charger’s power MOSFET is off, which effectively isolates the power...

One of the effective passive means you can use to suppress the ringing and clamp the overvoltages caused by the leakage energy in a flyback transformer is to implement a recuperating winding bifilar with the primary winding. This is the same technique commonly used to...

Most isolated, offline SMPSs (switched-mode power supplies), including flyback, forward, and resonant, must operate at input voltages of 90 to 260 V rms. Some cases even use line-to-line voltages of 400 V rms±10%, leading to increased component-voltage ratings and, thus,...
