EDN Magazine — 02.16.95 LIER circuit helps power-supply efficiency (figure)

FIGURE 1

Fig 1— This high-frequency, high-power, low-input-voltage, flyback-converter power supply conquers efficiency-killing parasitic effects. Energy recovered from the inductor's leakage inductance flows to C₃, from C₃ to L₁, and, last, from L₁ to C₀.
